We are using elasticsearch 1.3.7 cluster with 5 data only nodes and 3 master only nodes with 6 GB heap size for each node.
FYI,already we are in ES upgrading progress.
Today suddenly one node got removed , shards are gone to unassigned .
Data node got removed due to GC occurrence and Slow queries
Why we are getting this ClusterBlockException in data node failure?
We gone to cluster with master only and Data only nodes for avoid this ClusterBlockException because we already suffered this issue when master node (data cum master) failure occurs .
can you please help and suggest us!!
