BELUGA BEHR commented on HIVE-20233:
------------------------------------
In this last patch, I moved some of the logging to TRACE level. I suggest that
we make this change based on some recent troubleshooting I did. This logging
was pretty worthless and way too verbose. Note that there is still some DEBUG
logging in the method that also had TRACE level, so the method is still a bit
chatty, but not nearly as bad.
