Bulk loaded 28m documents to a new index with 0 replicas and with
refresh disabled using ES 0.19.2. After the initial import, the # of
replicas was set to 1 and reset the refresh interval to 1 second. Two
shards have been moving between 3 (of the 4) different nodes for
almost 12 hours.
None of the nodes were restarted after the import. Other possible
discovery.zen.ping.unicast.hosts: ["192.168.50.101", "192.168.50.102"]
Note that the unicast hosts only contain 2 out of the 4 hosts. Seems
to have worked well so far. The cluster is in development and none of
the settings (number of shards/replicas/nodes) have been tuned.
Working primarily on the import/search flow.
