Master node crash in elasticsearch


(satyendar duddukuri) #1

I want to know what happens if master node crash in elasticsearch.

  • does any other nodes in the cluster act as master node.
  • do we have to configure another node to act as master node in case of
    failover.
  • does es automatically recovers some how like recovering a shard from
    replica when primary shard crashes.

Please some one explain me on this subject as 'kimchy' also didn't answer
this question that was raised in another elasticsearch blog.

You can test it really easily. Just start some nodes and crash some of them.
