In usual circumstances when one Zookeeper goes down while others 2 are up,
Solr continues to operate but when one of the ZK machine was not reachable
with ping returning below results, Solr count't starts. See stack trace
below
ping: cannot resolve ditsearch001.es.com: Unknown host
Setup: Solr 6.6.2 and Zookeeper 3.4.10
I had to remove this server name from the ZK_HOST list (solr.in.sh) in
order to get Solr started. Ideally whatever issue is there as far as
majority is there, Solr should get started.
Has any one noticed this issue?
Thnx
