> 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).
