             Summary: Falcon server loses ability to communicate with HDFS over time
                 Key: FALCON-1595
                 URL: https://issues.apache.org/jira/browse/FALCON-1595
             Project: Falcon
          Issue Type: Bug
    Affects Versions: 0.8
            Reporter: Balu Vellanki
            Assignee: Balu Vellanki


In a kerberos secured cluster where the Kerberos ticket validity is one day, Falcon server eventually lost the ability to read and write to and from HDFS. In the logs we saw typical Kerberos-related errors like "GSSException: No valid credentials provided (Mechanism level: Failed to find any Kerberos tgt)".
