The elastic cluster consists of 5 primary nodes and 1 DR node.  
I was unable to authenticate the elastic cluster using elastic user(basic authentication).  
Also, I tried to curl -XGET -u elastic:password [http://localhost:9200/\_cluster/health?pretty](http://localhost:9200/_cluster/health?pretty). But this also not worked in this case. After checking the node connectivity to the cluster, I realized the DR node has isolated form the cluster.

I want to know what is the reason to unable to authenticate elastic user when DR node is isolated from the elastic cluster.  
Is there a way to maintain the elastic cluster in stable conditions in this scenario also.

A single node will never work properly if separated from the rest of the cluster so trying to handle DR this way is IMHO not going to work.

I would recommend instead setting up two separate clusters and either use CCR or index to them in parallel.
