Rui Li commented on HIVE-16047:
-------------------------------
The 2.2 branch is still building with Hadoop-2.7.2. My concern is if we revert
the patch in 2.2 and when the new Hadoop (containing the breaking change and
all the improvements) is released, we may find Hive-2.2 doesn't work with it
anyway due to other compatibility issues. Then users of Hive-2.2 will have to
live with the annoying logs. That's why I prefer to revert in master and keep
it in 2.2 (or 2.x).
