Zeppelin does not start and returns: params.zookeeper_znode_parent not in interpreter['properties']['phoenix.url']: KeyError: 'phoenix.url'

After the initial install of the cluster and trying to start up Zeppelin service the following comes up in Ambari

Traceback (most recent call last):

KeyError: 'phoenix.url'

WORKAROUND:
It is likely there are no phoenix properties in /etc/zeppelin/conf/interpreter.json file. In that situation:

• edit this file
• search for "jdbc"
• in that section go to "properties" where you can see definition for hive, default, etc.
• add the below:
  "phoenix.user": "phoenixuser",
  "phoenix.driver": "org.apache.phoenix.jdbc.PhoenixDriver",
  "phoenix.url": "jdbc:phoenix:<hbase.zookeeper.quorum>:<zookeeper.znode.parent>",
  "phoenix.hbase.client.retries.number": "1",
• save the changes
• restart Zeppelin

OR
Remove /etc/zeppelin/conf/interpreter.json file and restart Zeppelin service

Steps to reproduce; (this happens only on a Kerberos enabled cluster)

• On a fresh cluster install just Zeppelin
• Once the above is done, then installed hbase/phoenix.
• Now restart Zeppelin

Ambari will fail to start Zeppelin with the above-mentioned error.
