Getting MasterNotDiscoveredException multiple times

Elastic Stack Elasticsearch
1

Hi,

I am getting the following exceptions multiple times. And that makes me
restart all ES nodes.

Once I do that, everything comes back to normal.

org.elasticsearch.discovery.MasterNotDiscoveredException: waited for [1m]
at
org.elasticsearch.action.support.master.TransportMasterNodeOperationAction$3.onTimeout(TransportMasterNodeOperationAction.java:180)
at
org.elasticsearch.cluster.service.InternalClusterService$NotifyTimeout.run(InternalClusterService.java:492)
at
java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145)
at
java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615)
at java.lang.Thread.run(Thread.java:724)

Is there some configurations issue or so? There are total 5 nodes, out of
which for node, I have marked master flag to true.

Are you using multicast or unicast discovery?

Is this a continual pattern or a one time issue across multiple nodes?
