Elliott Clark commented on HBASE-15135:
---------------------------------------

-1 on 1.2 line. This is a feature, we should try and move quickly to the next minor release
instead of back porting.

> In order to make sure that compactions are fully up to date it would be nice to have
metrics on:
> * Max storefile age
> * Min storefile age
> * Average storefile age
> * Number of reference files
> If we could have those metrics per region and per regionserver it would be awesome.
