Jar Hell - ES1Engineer Training - Lab 2


Lab 2 - the installation of elasticsearch from ssh1 fails

[2021-04-23T00:09:21,542][ERROR][o.e.b.ElasticsearchUncaughtExceptionHandler] [server1] uncaught exception in thread [main]
org.elasticsearch.bootstrap.StartupException: java.lang.IllegalStateException: failed to load plugin x-pack-watcher due to jar hell

I am not sure what "jar hell" is though I think it is not good since it does not allow me to install


Could you share the full output?

JarHell indicates that a plugin tries to load a library which is already loaded but with another version or something else which conflicts.
