This Zookeeper ensemble doesn't look right.

Shouldn't the zookeeper ensemble be specified as:
  zk0-esohad:2181,zk1-esohad:2181,zk3-esohad:2181

You should put the zookeeper port on each node in the comma separated list.
I don't know if this is your problem, but I think your solr nodes will only
be connecting to 1 zookeeper
