-----------------------------------------

             Summary: Zookeeper dataDir can not be updated when using Ambari
                 Key: AMBARI-4242
                 URL: https://issues.apache.org/jira/browse/AMBARI-4242
             Project: Ambari
          Issue Type: Improvement
          Components: client
    Affects Versions: 1.2.4
            Reporter: Vitaly Brodetskyi
            Assignee: Vitaly Brodetskyi




If you install a cluster using Ambari your zookeeper Datadir is locked once the 
cluster is successfully installed. The option is permenantly greyed out and you 
cannot update it via the zoo.cfg (Ambari overwrites it)
You can, however, update it in the zoo.cfg and start zookeeper manually. When 
you start it through Ambari then it gets overwritten.

It would be good if you could modify this property via Ambari
(Maybe for best practice we could maybe add dataLogDir so logging and snapshots 
will not compete for the same disk I/O)
