URL: https://issues.apache.org/jira/browse/AMBARI-9963
Project: Ambari
Issue Type: Bug
Components: ambari-server
Affects Versions: 1.7.0
Reporter: Jayush Luniya
Assignee: Jayush Luniya
Fix For: 2.0.0
On a Kerberized cluster attempting to issue a 'rebalance' command via Ambari
1.7 UI results in the following:
15/02/26 16:02:40 WARN ipc.Client: Exception encountered while connecting to
the server : javax.security.sasl.SaslException: GSS initiate failed [Caused by
GSSException: No valid credentials provided (Mechanism level: Failed to find
any Kerberos tgt)]
Issuing a kinit via CLI first and then running the HDFS command manually works.
