> [root@elastic01 ~]# /usr/share/elasticsearch/bin/plugin  
> Error: Could not find or load main class org.elasticsearch.plugins.PluginManagerCliParser

early i was change /etc/sysconfig/elasticsearch:

> ES\_HOME=/home/elasticsearch  
> CONF\_DIR=/etc/elasticsearch  
> DATA\_DIR=/home/elasticsearch/lib

This may be the reason?

Hey,

I assume that setting `ES_HOME` to `/home/elasticsearch/` is the culprit. This means you are expecting your installation to be there, including the libraries.

You can verify by setting `set -x` in `/usr/share/elasticsearch/bin/plugin` in the second line and see which paths are being used when before the plugin manager is executed.
