-----------------------------------
Summary: Eliminate blocking call to scheduler for isguaranteed
Key: HIVE-23589
URL: https://issues.apache.org/jira/browse/HIVE-23589
Project: Hive
Issue Type: Improvement
Reporter: Mustafa Iman
Assignee: Mustafa Iman
LlapTaskCommunicator requires isGuaranteed information from LlapTaskScheduler
just before sending the actual request to the executor. There is no particular
ordering between the writing the submit request to the network and scheduler
decisions. Therefore, we can just put the initial isGuaranteed information in
task allocation rather than calling back scheduler.
Depends on https://jira.apache.org/jira/browse/TEZ-4192
