I'm using 3 nodes of ES 1.7.4 with Graylog2-1.3.
currently, one of ES node is a master, and 2 nodes are data node. and these nodes have 8GB of ram on each server.
and here's the problem : If I querying too big data, then one of data node crashes with OOM.
after than, master node automatically relocate shards and replicas.
but in most time, I can restart elasticsearch in very short time, so It seems doesn't need to relocate shard.
Is there anyway to stop auto-relocation some amount of time?
If I can stop it about 10~20 mins, It would be great.
