Wei Zheng commented on HIVE-14222:
----------------------------------
[~gopalv] Can you briefly put some explanation on how container reuse works
here? I talked to [~ashutoshc], he's not very convinced how that can happen,
given the understanding of how operator pipeline works - every time we are
creating a new object even using the same jvm.
