]

Elliott Clark resolved HBASE-3907.
----------------------------------

    Resolution: Not A Problem

>From what I can see the following are the issues that put the per cf metrics in:

* HBASE-4768
* HBASE-4809
* HBASE-4683
* HBASE-5072
* HBASE-5230
* HBASE-5274

Most of the work on the dynamic per cf, per table metrics went into 0.94.0. So I taged that
version and marking as resolved(Not A Problem)
