Jan Høydahl commented on SOLR-5129:
-----------------------------------
Do we support the usecase where people install ZK on the same servers as Solr,
and then the OS brings up all services at the same time (or random order) at
first start? Or do we require that there is an explicit delay between starting
ZK and starting Solr?
> If zookeeper is down, SolrCloud nodes will not start correctly, even if
> zookeeper is started later

> Summary of report from user on mailing list:
> If zookeeper is down or doesn't have quorum when you start Solr nodes, they
> will not function correctly, even if you later start zookeeper. While
> zookeeper is down, the log shows connection failures as expected. When
> zookeeper comes back, the log shows:
> INFO - 2013-08-09 15:48:41.528;
> org.apache.solr.common.cloud.ConnectionManager; Client->ZooKeeper status
> change trigger but we are already closed
> At that point, Solr (admin UI and all other functions) does not work, and
> won't work until it is restarted.
