-------------------------------------
Summary: Zeppelin Restart via Ambari Changes Permissions on log
folder which causes Permission issue for impersonated users
Key: AMBARI-25225
URL: https://issues.apache.org/jira/browse/AMBARI-25225
Project: Ambari
Issue Type: Bug
Components: ambari-server
Affects Versions: 2.6.2
Reporter: Akhil S Naik
Assignee: Akhil S Naik
Problem Statement : I am Using User impersonation for some of interpreters in
zeppelin , now that the interpreters write their own logs to the zeppelin log
directory. This becomes impossible if the users do not have permissions to
write to the zeppelin log directory. This is because while starting zeppelin
the Ambari changes the permission of zeppelin log directory to 0755 which makes
only Zeppelin user having having write permission in log directory.
expectation with user impersonation is, all the impersonating users will belong
to hadoop group (which is same as zeppelin, zeppelin also belong to hadoop) .
So Zeppelin Startup script should give 0775 Permission to /var/log/zeppelin
folder
