Description

Please find the versions I am using 

Apache Ranger ElasticSearch Plugin: ranger-2.2.0-elasticsearch-plugin.tar.gz

elasticsearch version: 7.6.0 

OS: Ubuntu 20.04.4

I installed the apache ranger elasticsearch plugin on elastic search host, while starting elasticsearch service I am getting below error:

Note: Without ranger plugin the elasticsearch plugin is working perfect. It would be very helpful if you redirect me to documentation on how to install ranger-2.2.0-elasticsearch-plugin.tar.gz on 7.6.0 & above.
