---------------------------------
Resolution: Fixed
> 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
> Priority: Major
>
> 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.
