Siddharth Wagle commented on AMBARI-12347:
------------------------------------------
The issue is with the Zookeeper principal generated for AMS is called
_amszk/<HOSTNAME>@<REALM>_
Without proper ACL setup Zookeeper does not work with custom principal name.
*Workaround*: is to use existing keytab if present on that host or create a new
keytab as _zookeeper/<HOSTNAME>@<REALM>_
> AMS does not work with Kerberization in distrbuted mode
