I have the config
cluster.routing.allocation.disk.watermark.high:85% and I notice that once a node cross 85% threshold, Elasticsearch starts relocating all shards out from that node.
It is strange to me because it'll drop below 85% if it just move one of them. Is there a config I can control on this? or is this a expected behavior for elasticsearch?
I'm using Elasticsearch 2.4.1
