Subject [jira] [Created] (AMBARI-3711) Installer wizard: Zookeeper service should be a requirement for Hive+WebHcat service.

Oleg Nechiporenko created AMBARI-3711:
-----------------------------------------

             Summary: Installer wizard: Zookeeper service should be a requirement for Hive+WebHcat
service.
                 Key: AMBARI-3711
                 URL: https://issues.apache.org/jira/browse/AMBARI-3711
             Project: Ambari
          Issue Type: Bug
          Components: client
    Affects Versions: 1.4.1
            Reporter: Oleg Nechiporenko
            Assignee: Oleg Nechiporenko
             Fix For: 1.4.1


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.
