Bugs: AMBARI-15645
https://issues.apache.org/jira/browse/AMBARI-15645
Repository: ambari
Description
-------
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
# 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)
```
It should probably be something like:
# 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)
```
# *Note the change from jn to hdfs in the kinit command line.*
