> Affects Versions: 2.1.2
> Reporter: Robert Levas
> Assignee: Robert Levas

> After upgrading HDP in Ambari version 2.1.2.1 a task a performed to _role
> edits_ while restarting JournalNodes. If Kerberos is enabled, the JN Kerberos
> identity is established before making this call when really the HDFS identity
> should be established - since this is an administrative HDFS call that
> requires the HDFS administrator user to perform.
> Because of this, the following error is generated and seen in the :
> {noformat}
> Fail: Execution of 'hdfs dfsadmin -rollEdits' returned 255. rollEdits: Access
> denied for user jn. Superuser privilege is required
> {noformat}
> The offending code is
> {code:title=common-services/HDFS/2.1.0.2.0/package/scripts/journalnode_upgrade.py}
> if params.security_enabled:
> Execute(params.jn_kinit_cmd, user=params.hdfs_user)
> time.sleep(5)
> hdfs_roll_edits()
> time.sleep(5)
> {code}
> It should probably be something like:
> {code:title=common-services/HDFS/2.1.0.2.0/package/scripts/journalnode_upgrade.py}
> if params.security_enabled:
> Execute(params.hdfs_kinit_cmd, user=params.hdfs_user)
> time.sleep(5)
> hdfs_roll_edits()
> time.sleep(5)
> {code}
> *Note the change from jn to hdfs in the kinit command line.*
> This issue has also been posted in
> https://issues.apache.org/jira/browse/AMBARI-10519.
