Elasticsearch-river-csv Error: "NoClassSettingsException[Failed to load class with value [csv]]; nested: ClassNotFoundException[csv];"

Elastic Stack Elasticsearch

Hi to all.

My name is Mohammad Rafi.
And i am new learner to this ElasticSearch.

I am using windows 7 64-bit
Elasticsearch version 0.19.8
and i have added HEAD and RIVER-CSV plugins to my elasticsearch.

I have gone through the following links to read csv-river plugin for
elastisearch.
"http://www.elasticsearch.org/guide/reference/modules/plugins.html" and
"https://github.com/xxBedy/elasticsearch-river-csv"

I have created "g:/me_demos/test01.csv" file in my file system. which
contain:
name,age,message
ram,12,hi ram
rakesh,22,hi rakesh.

And I have "g:/me_demos/insertrivercsv.json" file which contain:
{
"type" : "csv",
"csv_file" : {
"folder" : "/me_demos",
"filename_mask" : ".*\test01.csv$",
"poll":"5m",
"fields" : [
"name",
"age",
"msg"
],
"field_separator" : ",",
"escape_character" : ";",
"quote_character" : "'"
},
"index" : {
"index" : "my_csv_dat",
"type" : "csv_row",
"bulk_size" : 10000,
"bulk_threshold" : 50
}
}

I have tried to insert ".csv" file data to elasticsearch by using csv
river.
I have used curl command for inserting and it display as
curl -XPOST http://localhost:9200/_river/my_csv_river/_meta -d
@g:/me_demos/insertrivercsv.json
[image: curl ocmmand]
I have inserted only one _id that is "_meta".
but it inserted two _ids and they are _meta and _status.
_meta has some data but _status has error message. as below
[image: ES side error message]
But in Elasticsearch the .csv file is not inserted and also I got an error
message like:
NoClassSettingsException[Failed to load class with value [csv]]; nested:
ClassNotFoundException[csv];

can any one tell me why this is happening?
Suggest me, how to resolve it?
And also please tell me where should I get more documentation/information
about csv-river for Elasticsearch.

Thanks to you all.

Probably your plugin is not well setup.
Have look in your logs.

When you restart ES can you see the plugin name in logs as a plugin (not as a site plugin) ?

How did you install the plugin ?
Which is the ES version ?

hi, David..
Thanks you very much for responding.

Which is the ES version ?
I am using, elasticsearch-0.19.8 Version.

Probably your plugin is not well setup.
How did you install the plugin ?

This is the link which I followed the instructions to install,

In above link, it contain instructions like,

In order to install the plugin, simply run: bin/plugin -install
xxBedy/elasticsearch-river-csv/1.0.1.

If it doesn't work, clone git repository and build plugin manually.

| CSV Plugin | Elasticsearch |

| master | 0.19.x -> master |

| 1.0.1 | 0.19.x |

| 1.0.0 | 0.19.x |

I have tried to use "plugin -install xxBedy/elasticsearch-river-csv/1.0.1"
but it fails. Then again

I have used “plugin -install xxBedy/elasticsearch-river-csv/1.0.0” like:

C:\elasticsearch-0.19.8\elasticsearch-0.19.8\bin> plugin -install
xxBedy/elasticsearch-river-csv/1.0.0

And When I hit the enter key

Then it dispals "installed river-csv". consider the following image,

https://lh6.googleusercontent.com/-ZdgokSQ6JxY/UU_5mb657LI/AAAAAAAAAA0/YprpaRj0pLY/s1600/es_log_ins_csv.png

Have look in your logs.
When you restart ES can you see the plugin name in logs as a plugin (not
as a site plugin) ?

https://lh5.googleusercontent.com/-HyCa4aom6Ks/UU_5Ax2CEXI/AAAAAAAAAAs/IfRBmjwCIxI/s1600/es_ins_log.png

Thus in the above fig:, when i started the elasticsearch, in log it
displays the plugin details like:
[plugins][Killer Shrike] loaded , sites [ river-csv, head].

thus in the above i have river-csv in my elasticsearch.
did i have do any wrong while installation?

I have read "java-api, bulk indexing, ..." which will help me to do bulk
loading with java api from the source of elasticsearch.org
still I have many doubts
1.I don't know how to index .csv file into elasticsearch. please tell me
where can i get more information regarding to
" indexing .csv file ( which contain huge amount of documents to load )
contents using java api into elasticsearch".
2. how can i index .json file ( which contains 1million documents to load)
into Elasticsearch using java api?
3. what is the process for loading that huge amount of data?

Thanks you very much, David.

So the plugin is recognized as a site plugin, which is the issue.
It's a known problem due to some changes at github about download service.

You should try to build it yourself and unzip the ZIP file in your es/plugins/elasticsearch-river-csv dir.

Or wait for advices from the author :wink:

Hi to All.
good Evening.,

As per David suggestion,
I have downloaded zip file from the site:github regarding to
elasticserach-river-csv.
And i have done all the process, like
unzipping elasticsearch-river-csv.zip file into my
..\elasticsearch-0.19.8\elasticsearch-0.19.8\plugins directory.
and i have removed _river index feom my ES
Then again i started elasticsearch and tryed to insert .csv file data
into Elasticsearch.
but again it fails to load csv river.
I follwed below steps for inserting.....

curl -XPUT localhost:9200/_river/my_csv_river/_meta --data-binary
@democsvclient.json

in democsvclient.json file....
{
"type" : "csv",
"csv_file" : {
"folder" : "/test",
"filename_mask" : "csvdata.csv",
"poll":"5m",
"fields" : [
"user",
"age",
"dis"
],
"field_separator" : ",",
"escape_character" : ";",
"quote_character" : "'"
},
"index" : {
"index" : "my_csv_dat",
"type" : "csv_row",
"bulk_size" : 100,
"bulk_threshold" : 50
}
}

In my ES log, it shows exception like,

org.elasticsearch.common.settings.NoClassSettingsException: Failed to load

I think the statments I have written in democsvclient.json file is wrong.
which I was shown below.
In source of GitHub, instructions like:
{
...........

"csv_file" : {
    "folder" : "/tmp",      <------------
    "filename_mask" : ".*\\.csv$",   <----------

.......
}

In my democsvclient.json file
{
"type" : "csv",
"csv_file" : {
"folder" : "/test", <-----------
"filename_mask" : "csvdata.csv", <---------
...
....
}
If any one knows this issue please suggest me how to handle it.

can any one suggest me, what i have made mistake to insert .csv file data
into elasticsearch?
Also please tell me, Is there any alternate technique to handle *.csv file
and insert into elasticsearch?

You cannot use the zip file found on github. That zip file is merely the
contents of the repository bundled as a zip. You need to clone the repo and
build the plugin yourself. The resulting zip file is the one you need to
use.

Good morning to all,

hi Brusic,
Thank for your suggestion.

I have tried it but still i am getting the same Exception.

What I have done is,
I have cloned the Elasticsearch-river-csv from repo of github.
And placed it under
..\elasticsearch-0.19.8\elasticsearch-0.19.8\plugins directory.

   And again I have started the elasticsearch and done the all process

to insert my csvdata.csv file content into elasticsearch.
This time also i am getting the same Exception.

"org.elasticsearch.common.settings.NoClassSettingsException: Failed to load
class with value [csv]"

so, what I have to do for insert .csv file data into elasticsearch?
any one can suggest me, how to handle (bulk index using java-api) csv file
into elasticsearch?
Is there any other technique for it?

Regards..

Did you actually build the plugin? I don't see that step.

That github site should be updated to resolve the confusion.
