Description

This is a long standing problem and previously could be observed in regionserver metrics, but, we recently added logging for long running compactions, and this has exposed the issue in a new way, e.g.

2014-09-15 14:20:59,450 DEBUG [regionserver8120-largeCompactions-1410813534627]
compactions.Compactor: Compaction progress: 22683625/6808179 (333.18%), rate=162.08 kB/sec

The 'rate' reported in such logging is consistent and what we were really after, but the progress indication is clearly broken and should be fixed.
