Zeppelin does not start because phoenix.url cannot be found

StefanDunkler — Thu, 22 Jun 2017 15:30:16 GMT

Trying to start Zeppelin server from Ambari. This worked fine until once, when Ambari fails to start it with:

Traceback (most recent call last):
  File "/var/lib/ambari-agent/cache/common-services/ZEPPELIN/0.6.0.2.5/package/scripts/master.py", line 450, in <module>
    Master().execute()
  File "/usr/lib/python2.6/site-packages/resource_management/libraries/script/script.py", line 329, in execute
    method(env)
  File "/var/lib/ambari-agent/cache/common-services/ZEPPELIN/0.6.0.2.5/package/scripts/master.py", line 227, in start
    self.update_kerberos_properties()
  File "/var/lib/ambari-agent/cache/common-services/ZEPPELIN/0.6.0.2.5/package/scripts/master.py", line 302, in update_kerberos_properties
    and params.zookeeper_znode_parent not in interpreter['properties']['phoenix.url']:
KeyError: 'phoenix.url'

Didn't change any configs.
Restart of Ambari server/agents does not work

Ambari 2.5.0, HDP 2.6.0.3

@Stefan Kupstaitis-Dunkler

Can you please confirm it is Ambari 2.5.0?

I see that Line 302 where this is failing code matches Ambari 2.5.1 (not Ambari 2.5.0)

1. (Ambari 2.5.1) https://github.com/apache/ambari/blob/release-2.5.1/ambari-server/src/main/resources/common-services/ZEPPELIN/0.6.0.2.5/package/scripts/master.py#L301

2. (Ambari 2.5.0) https://github.com/apache/ambari/blob/release-2.5.0/ambari-server/src/main/resources/common-services/ZEPPELIN/0.6.0.2.5/package/scripts/master.py#L302

By any chance have you recently upgraded your ambari ? Also the Agent? Are the RPMs are of same version.

rpm -qa | grep ambari

@Jay SenSharma

thanks.

Yeah... forget that I upgraded yesterday. I have ambari-agent and ambari-server 2.5.1. ambari-infra-solr, ambari-metrics-collector,.... are still 2.5.0.3

As a workaround I uncommented the piece of code in the master.py file.

Is there another possible solution?

@Stefan Kupstaitis-Dunkler

Post install upgrades are necessary to be performed like AMS upgrade.

The piece of code that you removed is actually added there intentially to fix the issue reported in:

AMBARI-20888. wrong ZK parent node (hbase-unsecure) getting configured as part of the jdbc(phoenix) URL on ubuntu secured cluster.

Specially for kerberized environment.

Hi All,

I'm getting the same issue after kerberizing the cluster though it's a newly built one.

HDP-2.6.1.0

Ambari - 2.5.1.0

This is a bug in Ambari 2.5.1 [https://issues.apache.org/jira/browse/AMBARI-21473]

Resolution:

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