I'm very new to SolrCloud. When I tried restarting our tomcat server
running SolrCloud, I started getting this in our logs:
SEVERE:

I've tried restarting zookeeper, and we have HBase running on the same
ZooKeeper nodes so I know ZooKeeper is responding properly. I've tried
googling these errors, but the only advice I've seen is "restart
zookeeper." Can someone give me an idea of what is going on?
Thanks,
Mike
