Subject [jira] [Created] (HBASE-11979) Compaction progress reporting is wrong
Date Mon, 15 Sep 2014 21:28:36 GMT
Andrew Purtell created HBASE-11979:
--------------------------------------

             Summary: Compaction progress reporting is wrong
                 Key: HBASE-11979
                 URL: https://issues.apache.org/jira/browse/HBASE-11979
             Project: HBase
          Issue Type: Bug
            Reporter: Andrew Purtell
            Priority: Minor


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

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

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.
