> 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)
