Subject Re: Live update the zookeeper for SOLR

Is solr configured to point to exactly one host or to a list of the hosts
in the zookeeper ensemble? The zkHost value should contain all of the zk
hosts.

We had a similar issue where the solr instance was only pointing to zk1 and
none of the rest. It went down, and that resulted in the solr instance
being inaccessible since it can't find the rest of the zk ensemble.

Best,
Chris
