Subject [jira] [Commented] (HBASE-8060) "Num compacting KVs" diverges from "num compacted KVs" over time
Date Thu, 20 Jun 2013 17:50:21 GMT

    [ https://issues.apache.org/jira/browse/HBASE-8060?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13689442#comment-13689442

Lars Hofhansl commented on HBASE-8060:
--------------------------------------

I see. So it does not really change the meaning - it's still the number of KV compacted in
last compaction - it just corrects the value.

> 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?
