[MergeException[java.lang.NullPointerException] and All shards failed for phase: [query_fetch]

ElasticSearch_Users_ · February 6, 2015, 12:01am

Hello,

My environment has 1 linux server installed elasticsearch 1.4.2 with
default settings from rpm package. I use TransportClient to send requests
to elasticsearch. I recently changed to use rpm package. It has been
working fine for a couple of day. But today I saw the following errors when
I indexed a data set I had successfully indexed before and tried to query a
simple word. In the meantime, the server takes much longer time to index
and delete indices.

Yes, I am using IBM JDK. How do you detect it that? Does it show from the
log?

I know there is a Lucene IBM JVM bug. Is this related? What are the cause
of the above exceptions?

Thank you,

Cindy

I know this because I have seen this same IBM JDK bug in our tests many times.

I also wrote the code in question. NPE is not possible.
https://github.com/apache/lucene-solr/blob/lucene_solr_4_10_2/lucene/core/src/java/org/apache/lucene/codecs/lucene49/Lucene49NormsConsumer.java#L213

This is why we say, don't use IBM JDK with lucene.

It's really appreciated that you quickly pointed out the cause!!!

Actually I had posted a question in this forum trying to find out more
details about the IBM JVM bug and why I can't use IBM JVM. Now I knew it

I know this because I have seen this same IBM JDK bug in our tests many
times.

I also wrote the code in question. NPE is not possible.

https://github.com/apache/lucene-solr/blob/lucene_solr_4_10_2/lucene/core/src/java/org/apache/lucene/codecs/lucene49/Lucene49NormsConsumer.java#L213

This is why we say, don't use IBM JDK with lucene.

Yes, I am using IBM JDK. How do you detect it that? Does it show from
the
log?

I know there is a Lucene IBM JVM bug. Is this related? What are the
cause of
the above exceptions?

Thank you,

Cindy

Hello,

My environment has 1 linux server installed elasticsearch 1.4.2 with
default
settings from rpm package. I use TransportClient to send requests to
elasticsearch. I recently changed to use rpm package. It has been
working
fine for a couple of day. But today I saw the following errors when I
indexed a data set I had successfully indexed before and tried to
query
a
simple word. In the meantime, the server takes much longer time to
index
and
delete indices.
