Subject Re: deprecating (old) metrics in favor of metrics2 framework
Date Tue, 10 Jul 2012 04:05:00 GMT
+1 for deprecating and moving to metrics2 faster.
I'd normally make the same argument about deprecating that Lars H. made, but I think current
HBase metrics really need improvement, so if I had voting power I'd vote to drop old stuff
and move to metrics2 ASAP.
