After Migrating from ES 6.6 to 6.7 getting below runtime error

Elastic Stack Elasticsearch

We are trying to Migrate ES from 6.6 to 6.7 and got the below exception on runtime.

java.lang.NoSuchFieldError: LUCENE_6_4_1
	at org.elasticsearch.Version.<clinit>(Version.java:76) ~[elasticsearch-6.7.0.jar!/:6.7.0]
	at org.elasticsearch.common.logging.DeprecationLogger.<clinit>(DeprecationLogger.java:144) ~[elasticsearch-6.7.0.jar!/:6.7.0]

Hi @Yashpal_Singh,

this sounds like a problem with the installation (lucene core out of sync with elasticsearch). Which platform are you running this on and using which installation method (linux tar vs. rpm vs. docker etc.)?

You can likely check the version of the jar by using:

unzip -p lib/lucene-core-* META-INF/MANIFEST.MF | less

in addition to just looking at the filename.

Hi Henning,

Thanks for quick response, We are running our spring-boot project on Ubuntu OS.

Maven Dependency:

  <dependency>
        <groupId>org.elasticsearch</groupId>
        <artifactId>elasticsearch</artifactId>
        <version>6.6.0</version>
    </dependency>

Have plot the maven dependency tree, checked the version of Lucene and it seems correct.
org.apache.lucene:lucene-core:jar:7.7.0

Your previous post indicated you are migrating to ES 6.7, why are you depending on 6.6.0 ?

Hi Tim,

My bad, Have pasted the old dependency.

Updated dependency.

 <dependency>
    <groupId>org.elasticsearch</groupId>
    <artifactId>elasticsearch</artifactId>
    <version>6.7.0</version>
</dependency>

Hi @Yashpal_Singh,

I think we need a slightly deeper understanding of this to come to a resolution. A few questions:

  1. Is this a client program using the elasticsearch transport protocol or are you embedding the elasticsearch service into your program?
  2. The exception shown above, does that occur while starting the elasticsearch server or a client program?
  3. Not sure exactly how spring boot does class loading, but would it be possible to find out if any part of your application has another org.apache.lucene.util.Version version?
  4. Would it be possible to share the full stack trace?

@HenningAndersen Please find my reply inline.

  1. Is this a client program using the elasticsearch transport protocol or are you embedding the elasticsearch service into your program?

Yes its a client code, using elasticsearch high level REST client

  1. The exception shown above, does that occur while starting the elasticsearch server or a client program?

We got the above exception while creating elasticsearch query using Queriesbuilder, Please note that service bootup was successful.

  1. Not sure exactly how spring boot does class loading, but would it be possible to find out if any part of your application has another org.apache.lucene.util.Version version?

I Have plot the mvn dependency tree, I didn't get lucene-core dependency from any other source.

  1. Would it be possible to share the full stack trace?

Hi @Yashpal_Singh,

let us try to double check that the actual lucene jar in use has that field, using:

javap -cp lucene-core-7.7.0.jar org.apache.lucene.util.Version

Hi @Yashpal_Singh,

that looks fine. It looks like it somehow picked up another version of org.apache.lucene.util.Version.

I think the easiest route to find the cause is to use a debugger and break inside org.elasticsearch.Version and then examine the class loader in use to find out where the class is taken from.

Alternatively, it could make sense to setup a mini-example demonstrating the issue and share it here.

Hi Henning,

Thanks for the help, will try to dig deeper in our applicaiton dependencies :slight_smile:
