Wrong files are loaded while starting the installed OpenDistro elasticsearch server

[t-sivasakthi]

Describe the bug
I have installed OpenDistro plugin using the following command and created the following config files manually. I have configured the elasticsearch.yml file with the created pem files.

Insall OpenDistro Plugin: sudo /usr/share/elasticsearch/bin/elasticsearch-plugin install -b com.amazon.opendistroforelasticsearch:opendistro_security:1.11.0.0

Config files:

1. root-ca.pem
2. admin-key.pem
3. admin.pem
4. node-key.pem
5. node.pem

Configured in elasticsearch.yml,

But I got the following error while starting the server,

uncaught exception in thread [main]

Why it's expecting esnode.pem instead of using node.pem?

Kindly provide your thoughts on this
