Subject [jira] [Updated] (HBASE-9829) make the compaction logging less confusing
Date Thu, 24 Oct 2013 02:01:44 GMT

Sergey Shelukhin updated HBASE-9829:
------------------------------------

    Description: 
1) One of the most popular question from HBase users has got to be "I have scheduled major
compactions to run once per week, why are there so many".
We need to somehow tell the user, wherever we log that there is a "major" compaction, whether
it's a major compaction because that's what was in the request (from regular major compaction
or user request), or was it just promoted because it took all files. Esp. the latter should
be clear.
2) small vs large compaction threads and minor vs major compactions is confusing. Maybe the
threads can be named short and long compactions.
