             Summary:  Localization and log-aggregation will fail if hdfs 
delegation token expired after token-max-life-time
                 Key: YARN-2704
                 URL: https://issues.apache.org/jira/browse/YARN-2704
             Project: Hadoop YARN
          Issue Type: Sub-task
            Reporter: Jian He
            Assignee: Jian He

In secure mode, YARN requires the hdfs-delegation token to do localization and 
log aggregation on behalf of the user. But the hdfs delegation token will 
eventually expire after max-token-life-time.  So,  localization and log 
aggregation will fail after the token expires.
