I have given adequate information. Please provide the solution. ---

Where? I just want to be sure that I do have the right information. So please do it again and share the complete output. I looked at the source code and I don't understand how this can happen TBH. My next suggestion is to download in another dir the tar.gz 6.6.1 distribution (not the rpm one), unzip it and launch it locally. And see what is happening. May be you do have some ENV variables that are somewhat conflicting? That's what we can hopefully figure out if you test it. ---

@Nathan_Sowatskey did you upgrade from a previous version? ---

I removed the previous version, and then installed a new version. So, yes, this is an upgrade. Thanks Nathan ---

The solution here is to manually remove the `/usr/local/var/elasticsearch/plugins/` after an uninstall, and then you can install a new version. The same also applies to `/usr/local/var/lib/elasticsearch/`. Regards Nathan ---

Yeah, I uninstalled ES completely and install it again to get the service back. But do we have to uninstall and reinstall everytime we face this issue? If so how do we back up the data and restore in the new installation? Thanks, Subhas ---

Have just yum'd CentOS 7 and Elasticsearch fails to start with: > [2019-04-02T10:17:51,444][WARN][o.e.b.ElasticsearchUncaughtExceptionHandler] [es-node01] uncaught exception in thread [main] > org.elasticsearch.bootstrap.StartupException: java.lang.IllegalStateException: Duplicate key org.elasticsearch.plugins.PluginsService$Bundle@30acf5ab Have always had to remove and install the geo-ip plugins but believe those plugins are now modules? Not convinced uninstalling the installation is the correct route - is there a simpler route to getting ES running again? Regards Ed ---

I have the same problem after upgrading from 6.6.1 to 6.7.1. ---

If the geo-ip plugin is removed and the folder deleted (as per Nathan post) then the upgrade (in my case yum) is performed correctly to 6.7.1. Note I had an issue with KIbana and templates which turned out to be a permissions issue (topic launched in Kibana forum) and since fixed. Regards Ed ---

Thanks for the update. I've deleted the plugin directory. Additionally I submitted the following command: ./bin/elasticsearch-plugin remove --purge ingest-geoip After that, the elasticsearch engine started up again. I performed the installation under Ubuntu 16.04.06 LTS. Cheers Detlef ---
