Sergey Shelukhin commented on HIVE-13343:
-----------------------------------------

nit: is there some way to not use a field but return the list from the fn or have an out parameter? If it's not hard to change. Looks good otherwise. Should probably be documented.

> Due to performance reasons, we should disable use of hybrid grace hash join in llap when dynamic partition hash join is not used. With dynamic partition hash join, we need hybrid grace hash join due to the possibility of skews.
