> On HDP-1.x stack, we can install a cluster with Hive+WebHcat service without zookeeper
service. HCatalog can store metadata either in HDFS or Zookeeper depending on the value of
property _templeton.storage.class_.   We set it to _ZooKeeperStorage_ in stack definition
as  this is recommended   by the HCat component. 
> Not having zookeeper service with the property  _templeton.storage.class_ set to  _ZooKeeperStorage_
might be a serious problem. 
> Note: Ambari 1.2.0  release had zookeeper as a required service for Hive+WebHcat service.
