I am trying to view Namenode Logs in Ambari - I am login as admin but its giving dr.who (which I guess is permission issues)

@Artem Ervits The cluster is kerberized. I tried that but it didn't worked

If accessing the NameNode web UI indicates that you are "dr.who", then this likely indicates that the cluster is not performing authentication on HTTP endpoints. The logs URL requires administrator access, so it is inaccessible unless authenticated as an administrator.

Enabling HTTP authentication is a separate step from enabling Kerberos security, so it's possible that the cluster has done one but not the other. For full details on how to enable HTTP authentication, please refer to the Apache Hadoop documentation for HTTP Authentication.
