Hari Sankar Sivarama Subramaniyan updated HIVE-12675:
-----------------------------------------------------
Description: As more and more subcomponents of Hive (Tez, Optimizer) etc
are using PerfLogger to track the performance metrics, it will be more
meaningful to set the PerfLogger logging level to DEBUG. Otherwise, we will
print the performance metrics unnecessarily for each and every query if the
underlying subcomponent does not control the PerfLogging via a parameter on its
own. (was: As more and more subcomponents are Hive (Tez, Optimizer) etc are

to set the PerfLogger logging level to DEBUG. Otherwise, we will print the
performance metrics unnecessarily for each and every query if the underlying
subcomponent does not control the PerfLogging via a parameter.)
