I am having an 8 node cluster with 3 master nodes and rest data nodes. I want to connect Kibana with this cluster and so I am following an example to create a coordinator node on the kibana machine.
There are a few points I am confused about:
1: discovery.zen.ping.unicast.hosts [] Should this array also contain the IP of my Coordinating node on all the nodes?
2: If I am keeping the above on, should the coordinator node also contain the above property? Otherwise how is it going to detect the cluster?
With the above setting I am getting:
[NVMBD2BFM90V03] failed to send join request to master [{NVMBD2BFL90V01}{IlfzRrSHQCmHL3H3dN3vtQ}{lthHFbdqQ82Nv6goa8H9YQ}{10.141.172.105}{10.141.172.105:9300}], reason [RemoteTransportException[[NVMBD2BFL90V01][10.141.172.105:9300][internal:discovery/zen/join]]; nested: ConnectTransportException[[NVMBD2BFM90V03][127.0.0.1:9300] connect_timeout[30s]]; nested: IOException[Connection refused: 127.0.0.1/127.0.0.1:9300]; nested: IOException[Connection refused]; ]
I am able to telnet the above node from the coordinating node.
What do I miss here?
What is the minimal setting to get my coordinating node up and running?
