Andrew Purtell commented on HBASE-8060:
---------------------------------------

I simply ran LoadTestTool and then while refreshing the UI noticed divergence that increased
stepwise with splits looked like.

> I have been running what amounts to an ingestion test for a day or so. This is an all-in-one
cluster launched with './bin/hbase master start' from sources. In the RS stats on the master
UI, the "num compacting KVs" has diverged from "num compacted KVs" even though compaction
has been completed from perspective of selection, no compaction tasks are running on the RS.
I think this could be confusing -- is compaction happening or not?
> Or maybe I'm misunderstanding what this is supposed to show?
