[SPARK-11182] HDFS Delegation Token will be expired when calling
"UserGroupInformation.getCurrentUser.addCredentials" in HA mode
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.
