> 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.
