Corrupted ElasticSearch index?

bizzorama · February 11, 2014, 12:18pm

Hi,

I've noticed a very disturbing ElasticSearch behaviour ...
my environment is:

1 logstash (1.3.2) (+ redis to store some data) + 1 elasticsearch (0.90.10)

kibana

which process about 7 000 000 records per day,
everything worked fine on our test environment, untill we run some tests
for a longer period (about 15 days).

After that time, kibana was unable to show any data.
I did some investigation and it looks like some of the indexes (for 3 days
to be exact) seem to be corrupted.
Now every query from kibana, using those corrupted indexes - failes.

Errors read from elasticsearch logs:

org.elasticsearch.search.facet.FacetPhaseExecutionException:
Facet[terms]: failed to find mapping for Name* ... a couple of other
columns*
org.elasticsearch.search.facet.FacetPhaseExecutionException: Facet [0]:
(key) field [@timestamp] not found

... generaly all queries end with those errors

When elasticsearch is started we find something like this:

[2014-02-07 15:02:08,147][WARN ][transport.netty ] [Name] Message
not fully read (request) for [243445] and action
[cluster/nodeIndexCreated], resetting
[2014-02-07 15:02:08,147][WARN ][transport.netty ] [Name] Message
not fully read (request) for [249943] and action
[cluster/nodeIndexCreated], resetting
[2014-02-07 15:02:08,147][WARN ][transport.netty ] [Name] Message
not fully read (request) for [246740] and action
[cluster/nodeIndexCreated], resetting

And a little observations:

When using elasticsearch-head plugin, when querying records 'manually',
i can see only elasticsearch columns (_index, _type, _id, _score).
But when I 'randomly' select columns and overview their raw json they
look ok.

2, When I tried to process same data again - everything is ok

Is it possible that some corrupted data found its way to elasticsearch and
now whole index is broken ?
Can this be fixed ? reindexed or sth ?
This data is very importand and can't be lost ...

Best Regards,
Karol

Your error logs seem to indicate some kind of version mismatch. Is it
possible for you to test LS 1.3.2 against ES 0.90.9 and take a sample of
raw logs from those 3 days and test them through to see if those 3 days
work in Kibana? The reason I ask is because LS 1.3.2 (specifically the
elasticsearch output) was built using the binaries from ES 0.90.9.

Thanks.

Sorry for the delay.

Looks like you were right, after downgrading ES to 0.90.9 i couldn't
reproduce the issue in such manner.

Unfortunately, I found some other problems, and one looks like a blocker
....

After whole ES cluster powerdown, ES just started replaying 'no mapping for
... ' for each request.

Hi Bizzorama,

I had a similar problem with the same configuration than you gave.
ES ran since the 11th of February and was fed every day at 6:00 AM by 2 LS. Everything worked well (kibana reports were correct and no data loss) until I restarted yesterday ES
Among 30 index (1 per day), 4 were unusable and data within kibana report for the related period were unavailable.

I would like to know when you downgrade ES to 0.90.9 if you get back data (i.e you was able to show your data in kibana reports) ?

I will try to downgrade ES version as you suggested and will let you know more

Thanks for your answer

Hi,

it turned out that it was not a problem of ES version (we tested on both
0.90.10 and 0.90.9) but just a ES bug ...
after restarting pc or even just the service indices got broken ... we
found out that this was the case of missing mappings.
We observed that broken indices had their mappings corrupted (only some
default fields were observed).
You can check this by calling: http:\es_address:9200\indexName_mapping

Our mappings were dynamic (not set manually - just figured out by ES when
the records were incoming).

The solution was to add a static mapping file like the one described here:

(we added the default one).

I just copied mappings from a healty index, made some changes, turned it to
a mapping file and copied to the ES server.

Now everything works just fine.

Karol

Are you sure you didn't run out of disk space or file handles at some
stage, or have an OOM exception?

No, when things are running everything is ok, indexes break during
restart/powerdown

Are you sure you didn't run out of disk space or file handles at some
stage, or have an OOM exception?

Hi,

it turned out that it was not a problem of ES version (we tested on both
0.90.10 and 0.90.9) but just a ES bug ...
after restarting pc or even just the service indices got broken ... we
found out that this was the case of missing mappings.
We observed that broken indices had their mappings corrupted (only some
default fields were observed).
You can check this by calling: http:\es_address:9200\indexName_mapping

Our mappings were dynamic (not set manually - just figured out by ES when
the records were incoming).

The solution was to add a static mapping file like the one described here:

Elasticsearch Platform — Find real-time answers at scale | Elastic(we added the default one).

I just copied mappings from a healty index, made some changes, turned it
to a mapping file and copied to the ES server.

Now everything works just fine.

Hi Bizzorama,

I had a similar problem with the same configuration than you gave.
ES ran since the 11th of February and was fed every day at 6:00 AM by 2
LS.
Everything worked well (kibana reports were correct and no data loss)
until
I restarted yesterday ES
Among 30 index (1 per day), 4 were unusable and data within kibana report
for the related period were unavailable (same org.elasticsearch.search.
facet.FacetPhaseExecutionException: Facet[0]: (key) field [@timestamp]
not found)

Do you confirm when you downgraded ES to 0.90.9 that you retrieved your
data
(i.e you was able to show your data in kibana reports) ?

I will try to downgrade ES version as you suggested and will let you know
more

Thanks for your answer

Sorry for the delay.

Looks like you were right, after downgrading ES to 0.90.9 i couldn't
reproduce the issue in such manner.

Unfortunately, I found some other problems, and one looks like a blocker
....

After whole ES cluster powerdown, ES just started replaying 'no mapping
for ... ' for each request.

Your error logs seem to indicate some kind of version mismatch. Is it
possible for you to test LS 1.3.2 against ES 0.90.9 and take a sample of
raw logs from those 3 days and test them through to see if those 3 days
work in Kibana? The reason I ask is because LS 1.3.2 (specifically the
elasticsearch output) was built using the binaries from ES 0.90.9.

Thanks.

Hi,

I've noticed a very disturbing Elasticsearch behaviour ...
my environment is:

1 logstash (1.3.2) (+ redis to store some data) + 1 elasticsearch
(0.90.10) + kibana

which process about 7 000 000 records per day,
everything worked fine on our test environment, untill we run some
tests for a longer period (about 15 days).

After that time, kibana was unable to show any data.
I did some investigation and it looks like some of the indexes (for 3
days to be exact) seem to be corrupted.
Now every query from kibana, using those corrupted indexes - failes.

Errors read from elasticsearch logs:

org.elasticsearch.search.facet.FacetPhaseExecutionException:
Facet[terms]: failed to find mapping for Name* ... a couple of other
columns*

org.elasticsearch.search.facet.FacetPhaseExecutionException: Facet
[0]: (key) field [@timestamp] not found

... generaly all queries end with those errors

When elasticsearch is started we find something like this:

[2014-02-07 15:02:08,147][WARN ][transport.netty ] [Name]
Message not fully read (request) for [243445] and action
[cluster/nodeIndexCreated], resetting

Message not fully read (request) for [246740] and action
[cluster/nodeIndexCreated], resetting

And a little observations:

When using elasticsearch-head plugin, when querying records
'manually', i can see only elasticsearch columns (_index, _type, _id,
_score).
But when I 'randomly' select columns and overview their raw json
they look ok.

2, When I tried to process same data again - everything is ok

Is it possible that some corrupted data found its way to elasticsearch
and now whole index is broken ?
Can this be fixed ? reindexed or sth ?
This data is very importand and can't be lost ...

Best Regards,
Karol

Hi,

Thanks Karol, changing ES version does not change the problem indeed.

2 complementary questions if I may:

You wrote that you copied the mapping file on ES location, did you try a
way to do so dynamically with a REST call ?
Otherwise did you apply the modification for the specific "corrupted"
index or copy the mapping file in default config ES location (that is to
say that it was valid for all index ?)

Regards

José

Are you sure you didn't run out of disk space or file handles at some
stage, or have an OOM exception?

Hi,

it turned out that it was not a problem of ES version (we tested on
both 0.90.10 and 0.90.9) but just a ES bug ...

found out that this was the case of missing mappings.
We observed that broken indices had their mappings corrupted (only some
default fields were observed).
You can check this by calling: http:\es_address:9200
indexName_mapping

Our mappings were dynamic (not set manually - just figured out by ES
when the records were incoming).

The solution was to add a static mapping file like the one described
here:
Elasticsearch Platform — Find real-time answers at scale | Elastic
reference/current/mapping-conf-mappings.html (we added the default
one).

I just copied mappings from a healty index, made some changes, turned
it to a mapping file and copied to the ES server.

Now everything works just fine.

Hi Bizzorama,

I had a similar problem with the same configuration than you gave.
ES ran since the 11th of February and was fed every day at 6:00 AM by
2 LS.
Everything worked well (kibana reports were correct and no data loss)
until
I restarted yesterday ES
Among 30 index (1 per day), 4 were unusable and data within kibana
report
for the related period were unavailable (same org.elasticsearch.search.
facet.FacetPhaseExecutionException: Facet[0]: (key) field
[@timestamp] not found)

Do you confirm when you downgraded ES to 0.90.9 that you retrieved
your data
(i.e you was able to show your data in kibana reports) ?

I will try to downgrade ES version as you suggested and will let you
know
more

Thanks for your answer

Sorry for the delay.

Looks like you were right, after downgrading ES to 0.90.9 i couldn't
reproduce the issue in such manner.

Unfortunately, I found some other problems, and one looks like a
blocker ....

After whole ES cluster powerdown, ES just started replaying 'no
mapping for ... ' for each request.

Your error logs seem to indicate some kind of version mismatch. Is it
possible for you to test LS 1.3.2 against ES 0.90.9 and take a sample of
raw logs from those 3 days and test them through to see if those 3 days
work in Kibana? The reason I ask is because LS 1.3.2 (specifically the
elasticsearch output) was built using the binaries from ES 0.90.9.

Thanks.

Hi,

I've noticed a very disturbing Elasticsearch behaviour ...
my environment is:

1 logstash (1.3.2) (+ redis to store some data) + 1 elasticsearch
(0.90.10) + kibana

which process about 7 000 000 records per day,
everything worked fine on our test environment, untill we run some
tests for a longer period (about 15 days).

After that time, kibana was unable to show any data.
I did some investigation and it looks like some of the indexes (for 3
days to be exact) seem to be corrupted.
Now every query from kibana, using those corrupted indexes - failes.

Errors read from elasticsearch logs:

org.elasticsearch.search.facet.FacetPhaseExecutionException:
Facet[terms]: failed to find mapping for Name* ... a couple of other
columns*

org.elasticsearch.search.facet.FacetPhaseExecutionException: Facet
[0]: (key) field [@timestamp] not found

... generaly all queries end with those errors

When elasticsearch is started we find something like this:

[2014-02-07 15:02:08,147][WARN ][transport.netty ] [Name]
Message not fully read (request) for [243445] and action
[cluster/nodeIndexCreated], resetting

Message not fully read (request) for [246740] and action

And a little observations:

When using elasticsearch-head plugin, when querying records
'manually', i can see only elasticsearch columns (_index, _type, _id,
_score).
But when I 'randomly' select columns and overview their raw json
they look ok.

2, When I tried to process same data again - everything is ok

Is it possible that some corrupted data found its way to
elasticsearch and now whole index is broken ?
Can this be fixed ? reindexed or sth ?
This data is very importand and can't be lost ...

Karol

Hi, we tried both ways but:
First worked but was temporary and worked as index quickfix (after
powerdown it was lost again), of course we used the rest interfaces to fix
mappings that were already broken (we could not pump all data again so we
had to fix it somehow).

We applied the mapping file as default (for all indexes) to avoid the
problem in future, we knew that all indexes can be started with same
mapping.

Hi,

Thanks Karol, changing ES version does not change the problem indeed.

2 complementary questions if I may:

You wrote that you copied the mapping file on ES location, did you try a
way to do so dynamically with a REST call ?

Otherwise did you apply the modification for the specific "corrupted"
index or copy the mapping file in default config ES location (that is to
say that it was valid for all index ?)

José

Hi,

I am a little late but maybe it brings some closure...I believe you
ran into this: https://github.com/elasticsearch/elasticsearch/pull/5623
The symptoms for this bug are exactly what you describe.

Hi,

Thanks Karol, changing ES version does not change the problem indeed.

2 complementary questions if I may:

You wrote that you copied the mapping file on ES location, did you try
a way to do so dynamically with a REST call ?

Otherwise did you apply the modification for the specific "corrupted"
index or copy the mapping file in default config ES location (that is to say
that it was valid for all index ?)

Hi,

it turned out that it was not a problem of ES version (we tested on both
0.90.10 and 0.90.9) but just a ES bug ...
after restarting pc or even just the service indices got broken ... we
found out that this was the case of missing mappings.
We observed that broken indices had their mappings corrupted (only some
default fields were observed).
You can check this by calling: http:\es_address:9200\indexName_mapping

Our mappings were dynamic (not set manually - just figured out by ES
when the records were incoming).

The solution was to add a static mapping file like the one described
here:

Elasticsearch Platform — Find real-time answers at scale | Elastic
(we added the default one).

I just copied mappings from a healty index, made some changes, turned it
to a mapping file and copied to the ES server.

Now everything works just fine.

Hi Bizzorama,

I had a similar problem with the same configuration than you gave.
ES ran since the 11th of February and was fed every day at 6:00 AM by 2
LS.
Everything worked well (kibana reports were correct and no data loss)
until
I restarted yesterday ES
Among 30 index (1 per day), 4 were unusable and data within kibana
report
for the related period were unavailable (same
org.elasticsearch.search.facet.FacetPhaseExecutionException: Facet[0]: (key)
field [@timestamp] not found)

Do you confirm when you downgraded ES to 0.90.9 that you retrieved your
data
(i.e you was able to show your data in kibana reports) ?

I will try to downgrade ES version as you suggested and will let you
know
more

Thanks for your answer

Sorry for the delay.

Looks like you were right, after downgrading ES to 0.90.9 i couldn't
reproduce the issue in such manner.

Unfortunately, I found some other problems, and one looks like a
blocker ....

After whole ES cluster powerdown, ES just started replaying 'no mapping
for ... ' for each request.

Your error logs seem to indicate some kind of version mismatch. Is it
possible for you to test LS 1.3.2 against ES 0.90.9 and take a sample of raw
logs from those 3 days and test them through to see if those 3 days work in
Kibana? The reason I ask is because LS 1.3.2 (specifically the elasticsearch

Thanks.

Hi,

I've noticed a very disturbing Elasticsearch behaviour ...
my environment is:

1 logstash (1.3.2) (+ redis to store some data) + 1 elasticsearch
(0.90.10) + kibana

which process about 7 000 000 records per day,
everything worked fine on our test environment, untill we run some
tests for a longer period (about 15 days).

After that time, kibana was unable to show any data.
I did some investigation and it looks like some of the indexes (for 3
days to be exact) seem to be corrupted.
Now every query from kibana, using those corrupted indexes - failes.

Errors read from elasticsearch logs:

org.elasticsearch.search.facet.FacetPhaseExecutionException:
Facet[terms]: failed to find mapping for Name ... a couple of other columns

org.elasticsearch.search.facet.FacetPhaseExecutionException: Facet
[0]: (key) field [@timestamp] not found

... generaly all queries end with those errors

When elasticsearch is started we find something like this:

[2014-02-07 15:02:08,147][WARN ][transport.netty ] [Name]
Message not fully read (request) for [243445] and action
[cluster/nodeIndexCreated], resetting

Message not fully read (request) for [246740] and action
[cluster/nodeIndexCreated], resetting

And a little observations:

When using elasticsearch-head plugin, when querying records
'manually', i can see only elasticsearch columns (_index, _type, _id,
_score).
But when I 'randomly' select columns and overview their raw json
they look ok.

2, When I tried to process same data again - everything is ok

Is it possible that some corrupted data found its way to elasticsearch
and now whole index is broken ?
Can this be fixed ? reindexed or sth ?
This data is very importand and can't be lost ...

Best Regards,
Karol

I do see that @timestamp is defined in mapping file. May I Know why am I getting this issue ? I am using Elasticsearch-1.1.0 version, I tested with 0.90.9 as well, still get the same issue.

I do see that @timestamp is defined in mapping file. May I Know why am I getting this issue ? I am using Elasticsearch-1.1.0 version, I tested with 0.90.9 as well, still get the same issue.

We applied the mapping file as default (for all indexes) to avoid the

Hi,

Thanks Karol, changing ES version does not change the problem indeed.

2 complementary questions if I may:

You wrote that you copied the mapping file on ES location, did you
try
a way to do so dynamically with a REST call ?

Otherwise did you apply the modification for the specific
"corrupted"
index or copy the mapping file in default config ES location (that is
to say
that it was valid for all index ?)

Hi,

it turned out that it was not a problem of ES version (we tested on
both
0.90.10 and 0.90.9) but just a ES bug ...
after restarting pc or even just the service indices got broken ...
we
found out that this was the case of missing mappings.
We observed that broken indices had their mappings corrupted (only
some
default fields were observed).
You can check this by calling:
http:\es_address:9200\indexName_mapping

Our mappings were dynamic (not set manually - just figured out by ES
when the records were incoming).

The solution was to add a static mapping file like the one described
here:

Elasticsearch Platform — Find real-time answers at scale | Elastic

(we added the default one).

I just copied mappings from a healty index, made some changes, turned
it
to a mapping file and copied to the ES server.

Now everything works just fine.

Thanks for your answer

Sorry for the delay.

Looks like you were right, after downgrading ES to 0.90.9 i couldn't
reproduce the issue in such manner.

Unfortunately, I found some other problems, and one looks like a
blocker ....

After whole ES cluster powerdown, ES just started replaying 'no
mapping
for ... ' for each request.

possible for you to test LS 1.3.2 against ES 0.90.9 and take a

Hi,

I've noticed a very disturbing Elasticsearch behaviour ...
my environment is:

1 logstash (1.3.2) (+ redis to store some data) + 1 elasticsearch
(0.90.10) + kibana

which process about 7 000 000 records per day,
everything worked fine on our test environment, untill we run some
tests for a longer period (about 15 days).

After that time, kibana was unable to show any data.
I did some investigation and it looks like some of the indexes (for
3
days to be exact) seem to be corrupted.
Now every query from kibana, using those corrupted indexes -
failes.

Errors read from elasticsearch logs:

org.elasticsearch.search.facet.FacetPhaseExecutionException:
Facet[terms]: failed to find mapping for Name ... a couple of other
columns

org.elasticsearch.search.facet.FacetPhaseExecutionException:
Facet
[0]: (key) field [@timestamp] not found

... generaly all queries end with those errors

When elasticsearch is started we find something like this:

[2014-02-07 15:02:08,147][WARN ][transport.netty ] [Name]
Message not fully read (request) for [243445] and action
[cluster/nodeIndexCreated], resetting

Message not fully read (request) for [246740] and action

And a little observations:

When using elasticsearch-head plugin, when querying records
'manually', i can see only elasticsearch columns (_index, _type,
_id,
_score).
But when I 'randomly' select columns and overview their raw
json
they look ok.

2, When I tried to process same data again - everything is ok

Is it possible that some corrupted data found its way to
elasticsearch
and now whole index is broken ?
Can this be fixed ? reindexed or sth ?
This data is very importand and can't be lost ...

Karol

Hi all,

This is an old post, but had the same issue today.
It is because kibana searches in all indices by default, and kibana-int
(where the kibana interface data is stored)
has no timestamp field in it.

The error is gone after putting the correct index filter in the dashboard
settings.
