After error I've changed the permission in java.policy as per below URL

> **[couchbaselabs/elasticsearch-transport-couchbase](https://github.com/couchbaselabs/elasticsearch-transport-couchbase)**
>
> elasticsearch-transport-couchbase - A plugin for ElasticSearch that enables loading data using Couchbase XDCR

  
I've also provided couchbase username , password and port in elasticsearch.yml  
But still I'm getting error 1.
