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. -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

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