Automatic partial shutdown of cluster


(krishnan) #1

Hi All,

I have cluster of one master only nodes and 7 data only nodes. Some nodes
are getting shutdown automatically. Could you please advise what is the
possible cause of this behaviour or how do I investigate the issue.

For you perusal the log entry is below :

Something is shutting your node down using the API.

You might want to look at
http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/cluster-nodes-shutdown.html#_disable_shutdown

Thank you so much for the suggestion, Walkom.
Now how do I find out what is shutting down my nodes? I checked /var/logs,
did not find any thing suspicious. is this related to out of memory system
states.

Krishna
