[jira] [Created] (HADOOP-11113) Namenode not able to reconnect to KMS after KMS restart

Arun Suresh created HADOOP-11113:
------------------------------------

             Summary: Namenode not able to reconnect to KMS after KMS restart
                 Key: HADOOP-11113
                 URL: https://issues.apache.org/jira/browse/HADOOP-11113
             Project: Hadoop Common
          Issue Type: Bug
          Components: security
            Reporter: Arun Suresh
            Assignee: Arun Suresh


It is observed that if KMS is restarted without the Namenode being restarted, NN will not be able to reconnect with KMS.
It seems that the KMS auth cookie goes stale and it does not get flushed, so the KMSClient in the NN cannot reconnect with the new KMS.
