Ashutosh Chauhan commented on HIVE-20560:
-----------------------------------------
Can't access test report anymore. But I presume its because of plan changes. If
so, it will be better to retain original plan for these queries. So, we can set
old value of the config in .q file at beginning set
hive.llap.memory.oversubscription.max.executors.per.query = 3; and reset
hive.llap.memory.oversubscription.max.executors.per.query; at the end to get
these tests to pass.
> Set hive.llap.memory.oversubscription.max.executors.per.query to be 1/3rd of
> num of llap daemons

> Unless hive.llap.memory.oversubscription.max.executors.per.query is not
> specified by the user,
> it should be calculated like this:
> {noformat}
> hive.llap.memory.oversubscription.max.executors.per.query = min(max(1,
> int(hive.llap.daemon.num.executors / 3)),8)
> {noformat}
> In container mode it remains 3 (unless specified otherwise).
