Subject [jira] [Commented] (HBASE-8299) ExploringCompactionPolicy can get stuck in rare cases.
Date Tue, 09 Apr 2013 21:50:17 GMT

    [ https://issues.apache.org/jira/browse/HBASE-8299?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13627158#comment-13627158

Elliott Clark commented on HBASE-8299:
--------------------------------------

I don't understand what you're looking for.  You're asking to change the whole algorithm without
specific requests.  If you want to propose another algorithm for compaction selection then
another issue would be best.

As it stands now ExploringCompactionPolicy is broken and either needs to be changed so that
it can't get stuck (done in this patch) or ExploringCompactionPolicy needs to be removed (breaking
bulk loads again).

> If the files are very oddly sized then it's possible that ExploringCompactionPolicy can
get stuck.
