-----------------------------------
Summary: Increase the number of parallel tasks sent to daemons
from am
Key: HIVE-23747
URL: https://issues.apache.org/jira/browse/HIVE-23747
Project: Hive
Issue Type: Sub-task
Reporter: Mustafa Iman
Assignee: Mustafa Iman
The number of inflight tasks from AM to a single executor is hardcoded to 1
currently([https://github.com/apache/hive/blob/master/llap-client/src/java/org/apache/hadoop/hive/llap/tez/LlapProtocolClientProxy.java#L57]
). It does not make sense to increase this right now as communication between
am and daemons happen synchronously anyway. After resolving
https://issues.apache.org/jira/browse/HIVE-23746 this must be increased to at
least number of execution slots per daemon.
