Hi
I am having three node cluster in my environments and got an error like this as below.
when i checked in marvel... it shows an Request timeouterror in the status(RED).
"[2017-06-21 14:14:22,324][DEBUG][action.admin.indices.get ] [datanode-2] timed out while retrying [indices:admin/get] after failure (timeout [30s])"
"[2017-06-21 14:14:22,324][WARN ][rest.suppressed ] path: /_mapping, params: {index=_mapping}
MasterNotDiscoveredException[null]
at org.elasticsearch.action.support.master.TransportMasterNodeAction$AsyncSingleAction$5.onTimeout(TransportMasterNodeAction.java:234)"
