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.
> Deprecate metrics v1
