[jira] [Created] (MAPREDUCE-3398) Log Aggregation broken in Secure Mode

Log Aggregation broken in Secure Mode
-------------------------------------

                 Key: MAPREDUCE-3398
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-3398
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: mrv2, nodemanager
    Affects Versions: 0.23.0
            Reporter: Siddharth Seth
            Assignee: Siddharth Seth
            Priority: Critical


Log aggregation in secure mode does not work with MAPREDUCE-2977. The nodemanager relies on the users credentials to write out logs to HDFS. These credentials are currently cancelled once a job completes, before the NM can write out the logs.
