Subject [jira] [Commented] (HBASE-7893) hbase.hregion.majorcompaction not taking effect.
Date Fri, 22 Feb 2013 06:18:13 GMT

    [ https://issues.apache.org/jira/browse/HBASE-7893?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13583954#comment-13583954

Anoop Sam John commented on HBASE-7893:
---------------------------------------

As per your log sample, it was a minor compaction on all the store files. Now the extra work
as part of major compaction will be to deal with the delete markers. That makes RS to die?
I agree that the long running major compaction on all the files (large number) interfere with
your job. That is why you dont want that to happen automatically in your system (You might
be doing this manually)

> For disabling auto major compaction, I configured hbase.hregion.majorcompaction = 0 in
the config file and restarted the cluster. In spite of this, major compaction continues to
run everyday. Here is the config I set:
> <property>
>   <name>hbase.hregion.majorcompaction</name>
>   <value>0</value>
> </property>
> What other way can I disable auto major compaction? I expected this config to work. What
am I doing wrong here? 
> Please advice. Thanks a lot.
