I'm using Elastic Stack 6.4.0 (did rolling upgrade from 6.3.2 recently) and after stop of entire elasticsearch cluster (master, data, coordinate and ingest nodes), I'm no longer able to start it; I'm getting following messages in logs:
timed out while waiting for initial discovery state - timeout: 30s
and also:
org.elasticsearch.discovery.MasterNotDiscoveredException: null
I use Zen Discovery
and publish_host
seems to be correct.
Please advise.
