Liangliang Gu created SPARK-11182:
-------------------------------------

             Summary: HDFS Delegation Token will be expired when calling "UserGroupInformation.getCurrentUser.addCredentials" in HA mode
                 Key: SPARK-11182
                 URL: https://issues.apache.org/jira/browse/SPARK-11182
             Project: Spark
          Issue Type: Bug
          Components: YARN
            Reporter: Liangliang Gu


In HA mode, DFSClient will generate HDFS Delegation Token for each Name Node automatically, which will not be updated when Spark update Credentials for the current user.
Spark should update these tokens in order to avoid Token Expired Error.
