[jira] [Updated] (HIVE-21646) Tez: Prevent TezTasks from escaping
thread logging context
[ https://issues.apache.org/jira/browse/HIVE-21646?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Gopal V updated HIVE-21646:
---------------------------
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.
