Prabhu Joseph created HADOOP-14299:
--------------------------------------

             Summary: Hadoop Renew Thread for proxy users
                 Key: HADOOP-14299
                 URL: https://issues.apache.org/jira/browse/HADOOP-14299
             Project: Hadoop Common
          Issue Type: Bug
          Components: hdfs-client
    Affects Versions: 2.7.1
            Reporter: Prabhu Joseph


Currently Hadoop Client has a separate renew thread which is created only for Authentication type Kerberos and not for Proxy. So for proxy users, a yarn client monitoring a long running job will fail after initial ticket lifetime with GSS initiate failed unless there is a manual re-kinit.
