Akira AJISAKA commented on HADOOP-7266:
---------------------------------------

bq. I think we cannot say it's clean code by fixing warnings with SuppressWarning annotation,
unfortunately  It's just a workaround to make a illusion of clean code.
Agree.

bq. To make the code clean in this case, we need to replace them with metrics v2 code.
If we are to replace metrics1 code with metrics2, old configuration for ShuffleClientMetrics
and LocalJobRunnerMetrics will not work.
