---------------------------------
Resolution: Fixed
Fix Version/s: Impala 2.11.0
IMPALA-5541: Reject BATCH_SIZE greater than 65536
Setting a very large value could cause strange behaviour like crashing,
hanging, excessive memory usage, spinning etc. This patch rejects values
out of the range [0,65536].

> We don't enforce maximums on BATCH_SIZE. Setting a very large value could
> cause strange behaviour like crashing, hanging, excessive memory usage,
> spinning etc.
> I think a limit like 65536 (64x the default) would be reasonable but it's
> worth discussing further.
