-------------------------------------
I'll try to make a summary of the discussion that happened aroudn this over in
Accumulo. Over there, we just switched to start using Hadoop Metrics 2 in the
recent 1.7.0 release: ACCUMULO-1817
> Remove metrics2
> ---------------
>
> Key: HBASE-14282
> URL: https://issues.apache.org/jira/browse/HBASE-14282
> Project: HBase
> Issue Type: Improvement
> Components: metrics
> Reporter: Elliott Clark
> Priority: Critical
> Fix For: 2.0.0
>
>
> Metrics2 has a whole bunch of race conditions and weird edges because of all
> of the caching that metrics2 does.
> Additionally tying something so integral to hadoop who has lots of versions
> we support has been a maintenance nightmare. It would allow us to completely
> get rid of the compat modules.
> Rip it out.
