Lefty Leverenz commented on HIVE-15159:
---------------------------------------
No doc needed, because HIVE-15347 changes the default value of
*hive.llap.daemon.memory.per.instance.mb* back to its original value in the
same release as this issue.
Removing the TODOC2.2 label.
> LLAP ContainerRunner should not reduce the available heap while distributing

> hive.llap.daemon.memory.per.instance.mb is set to the heapsize of the process
> when llap service driver is used.
> ContainerRunner currently cuts this down to 80% of the available. This
> reduction is not necessary if the heapsize is used, instead of a container
> size.
