>          Issue Type: Bug

>            Reporter: Zack Marsh
>         Attachments: ambari-metrics-collector.log
> On an HDP cluster using Ambari 2.1.0 Kerberos has been enabled via Ambari's Kerberos
Wizard. Kerberos was enabled using an existing MIT KDC and the box for "Manage Kerberos client
krb5.conf" was unchecked.
> After the Kerberos Wizard completes and all of the Hadoop services are started, the Ambari
Metrics Collector consistently stops running.
> The ambari-metrics-collector.log [attached] is filled with the following error message:
> {code}
> 18:16:27,431  INFO [main] ConnectionManager$HConnectionImplementation:1613 - getMaster
attempt 23 of 35 failed; retrying after sleep of 20178, exception=org.apache.hadoop.hbase.MasterNotRunningException:
The node /ams-hbase-secure is not in ZooKeeper. It should have been written by the master.
Check the value configured in 'zookeeper.znode.parent'. There could be a mismatch with the
one configured in the master.
> {code}
> The value for "zookeeper.znode.parent" in the Ambari Metrics Collector's hbase-site.xml
is set to "/ams-hbase-secure".
> I see that ams-hbase-secure is not in Zookeeper:

> [hive, hiveserver2, zookeeper, hbase-unsecure, yarn-leader-election, hadoop-ha, oozie,
rmstore, hbase-secure, services]
> {code}
> Is this something that should have been handled in Ambari's Kerberos Wizard?
