Bugs: AMBARI-21769
https://issues.apache.org/jira/browse/AMBARI-21769
Repository: ambari
Description
-------
In a cluster where the Spark and/or Spark2 Livy servers and Zeppelin are
installed and Kerberos is enabled, it is expected that that
`livy-conf/livy.superusers` and `livy2-conf/livy.superusers` contain the
principal name of the Zeppelin user. However, this value is not always set,
depending on the order in which the services were installed, when Kerberos was
enabled, and whether an Ambari or stack upgrade was involved. And if it is
set, the value may be incorrect since the Kerberos descriptor assumes the
Zeppelin principal is `zeppelin-<clustername>`
The solution is to move the logic to set the `livy-conf/livy.superusers` and
`livy2-conf/livy.superusers` to the stack advisor to the appropriate value can
be added as needed. Also while upgrading to Ambari 2.5.2, the value(s) should
be fixed if necessary.
