I stopped one of my elastic search node & as a normal behavior elastic
search started relocating my shard on that node to another node.
But even after 15 hours it is still stuck in INITIALIZING state. Also that
shard is fluctuating between two nodes,for some time it stays on one node
then automatically shift to another node & keep on doing that after every
Main issue is it is still in INITIALIZING state after so many hours.
I am using version 1.2.1.
This shard which is stuck, it is a replica.
I am getting this error in logs:
[ERROR][index.engine.internal ] [mynode] [myindex] failed to
acquire searcher, source delete_by_query
[WARN ][index.engine.internal ] [mynode] [myindex] failed engine [
