Tez: Prevent TezTasks from escaping thread logging context

    Details

    • Type: Bug
    • Status: Resolved
    • Priority: Major
    • Resolution: Fixed
    • Affects Version/s: None
    • Fix Version/s: 4.0.0
    • Component/s: Tez
    • Labels:
      None

      Description

      If hive.exec.parallel is set to true to parallelize MoveTasks or StatsTasks, the Tez task does not benefit from a new thread and will lose all the thread context of the current query.

      Multiple threads even if they are spawned, will lock on SyncDagClient & make progress sequentially.
