Elasticsearch service start failed

That can't be, Elasticsearch specifies its own GC settings in the startup scripts / service definition.

I am sure I have not touched even a letter here

Your problem is this, you appear to have a botched plugin installation. I suggest removing that plugin and trying again. Also, I note that you appear to be running version 2.1.0 of Elasticsearch with version 2.3.3 of a plugin? If that's the official graph plugin, that will not work.

yes that's completely official graph ) Also it was not working with 2.1.0 but kibana was working well before alongside.
I had planned an upgrade using Rolling Restarts | Elasticsearch: The Definitive Guide [2.x] | Elastic
but it went down completely.
It worked when I removed Graph.

Thank you for the help.
