Error during startup

Soren_vdc · March 17, 2023, 2:31pm

Hi,

I receive this error during startup:
[ERROR][o.e.b.Elasticsearch ] [s2ab00jb.be.srv.dev.sys] fatal exception while booting Elasticsearch
java.lang.IllegalArgumentException: Could not load codec 'Lucene94'. Did you forget to add lucene-backward-codecs.jar?

Caused by: java.lang.IllegalArgumentException: An SPI class of type org.apache.lucene.codecs.Codec with name 'Lucene94' does not exist. You need to add the corresponding JAR file supporting this SPI to your classpath. The current classpath supports the following names: [Lucene92, Lucene70, Lucene80, Lucene84, Lucene86, Lucene87, Lucene90, Lucene91, BWCLucene70Codec, Lucene62, Lucene60, SimpleText]

What may cause this?
thx!

What version of Elasticsearch are you running?
What does yout config look like?
What is the full log?

Hi,

Version: 8.6.2, Build: rpm/2d58d0f136141f03239816a4e360a8d17b6d8f29/2023-02-13T09:35:20.314882762Z, JVM: 19.0.2

You want to see something specific from the config?

All of it please. Same with the log.

dadoonet · March 20, 2023, 8:15am

You said Elasticsearch 8.6.2 but the version running is elasticsearch-8.4.2.jar.

Did you try to downgrade?

Soren_vdc · March 20, 2023, 8:58am

Hi David,

Good remark! I have checked and it seems there was an downgrade triggered some time ago. I have tried to reinstall version 8.6.2 but still the same error during startup. Any idea?

dadoonet · March 20, 2023, 9:10am

Could you share the full logs again?

Soren_vdc · March 20, 2023, 9:51am

Hi David,

Elasticsearch is running again after update to version 8.6.2. So it seems the downgrade cause the issue. Thanks for the help!
