Siddharth Seth commented on HIVE-13343:
---------------------------------------
Can we please add an override for this. There's a parallel jira which will
cause regular map joins to fail in LLAP if they exceed memory limits. In that
case, the user should at least be able to run the query in LLAP - even if it is
with degraded performance.
> Need to disable hybrid grace hash join in llap mode except for dynamically
> partitioned hash join

> 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.
