Subject [jira] [Commented] (HBASE-8299) ExploringCompactionPolicy can get stuck in rare cases.
Date Tue, 09 Apr 2013 18:26:16 GMT

    [ https://issues.apache.org/jira/browse/HBASE-8299?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13626914#comment-13626914
] 

Sergey Shelukhin commented on HBASE-8299:
-----------------------------------------

The intuitive reason to compact 10 1 100 (for example) from [ 10 1 100 5000 1 ] is relative
size to the 5000 file. Maybe that could be encoded in a heuristic.

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