Sergey Shelukhin commented on HIVE-16015:
-----------------------------------------
A lot of different logging is useful for a lot of different issues. We disable,
for instance, ZK logging, even though recently I've been looking at issues
where having detailed ZK logging would be useful; because generally it's not
useful and the amount of it writes in unacceptable... the 2 of these 4 classes
in some cases constitute ~50% of all logging. I don't think they are as useful
as all other logging combined :) They clearly log debug data on info... so I
don't think we should enable until Hive officially switched to 0.90. Before
that it should be disabled.
