Elliott Clark commented on HBASE-14282:
---------------------------------------
[~busbey] Yeah switching to dropwizards was my thought. Metrics2 has just been
awful to work with.
* It tries to cache things in places that make working with it hard.
* Removing metrics is awful at best.
* Adding more metrics means way too much work.
* It's testability is awful because hadoop mangles names.
> Remove metrics2

> 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.
