Subject [jira] Commented: (HBASE-2457) RS gets stuck compacting region ad infinitum
Date Fri, 16 Apr 2010 05:45:25 GMT

    [ https://issues.apache.org/jira/browse/HBASE-2457?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12857682#action_12857682

Todd Lipcon commented on HBASE-2457:
------------------------------------

Looks like the compaction code is basically deciding that there's nothing worth compacting
here. Here are the files in the order that the compaction code is looking at them (oldest
to newest) with their sizes

> Testing 0.20_pre_durability@934643, I ended up in a state where one region server got
stuck compacting a single region over and over again forever. This was with a special config
with very low flush threshold in order to stress test flush/compact code.
