Nodes not communicating to other nodes in Search Landing page
I have 20 nodes in production. I am unable to add search node configuration in the slave node at search landing page. The master node showing offline in slave node search index page itself. We are getting below mentioned Error on the node startup.
Node could not join cluster at node: xxx.xx.xxx.xxAddress Cause: the target cluster has a different group-name [cluster]
Address xx.xx.xx.xx is added to the blacklist.
