zhangyubiao commented on YARN-5995:
-----------------------------------

Thanks [~sunilg] .  IMO, Histogram belong com.codahale.metrics  package , MutableCounter belong
org.apache.hadoop.metrics2.lib package,If we use these two metrics counter .it will mess up
the metrics lib.
So,I think it's better to write a MutableHistogram,MutableTimeHistogram reference HBase's
MutableHistogram,MutableTimeHistogram.  What do you thought,[~sunilg] ?
