Mustafa Iman created HIVE-23596: ----------------------------------- Summary: Encode guaranteed task information in containerId Key: HIVE-23596 URL: https://issues.apache.org/jira/browse/HIVE-23596 Project: Hive Issue Type: Improvement Reporter: Mustafa Iman Assignee: Mustafa Iman
We should avoid calling LlapTaskScheduler to get initial isguaranteed flag for all the tasks. It causes arbitrary delays in sending tasks out. Since communicator is a single thread, any blocking there delays all the tasks. There are [https://jira.apache.org/jira/browse/TEZ-4192] and [https://jira.apache.org/jira/browse/HIVE-23589] for a proper solution to this. However, that requires a Tez release which seems far right now. We can replace the current hack with another hack that does not require locking. -- This message was sent by Atlassian Jira (v8.3.4#803005)
