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

             Summary: Zeppelin does not start and returns: params.zookeeper_znode_parent not
in interpreter['properties']['phoenix.url']: KeyError: 'phoenix.url'
                 Key: AMBARI-21473
                 URL: https://issues.apache.org/jira/browse/AMBARI-21473
             Project: Ambari
          Issue Type: Bug
            Reporter: Prabhjyot Singh
            Assignee: Prabhjyot Singh


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

{code}
Traceback (most recent call last):
  File "/var/lib/ambari-agent/cache/common-services/ZEPPELIN/0.6.0.2.5/package/scripts/master.py",
line 448, in <module>
    Master().execute()

line 300, in update_kerberos_properties
    and params.zookeeper_znode_parent not in interpreter['properties']['phoenix.url']:
KeyError: 'phoenix.url'
{code}

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.
