Subject [jira] Commented: (HDFS-758) Improve reporting of progress of decommissioning
Date Mon, 09 Nov 2009 21:16:32 GMT

    [ https://issues.apache.org/jira/browse/HDFS-758?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12775149#action_12775149

Brian Bockelman commented on HDFS-758:
--------------------------------------

This would be incredibly useful for our site.  We find that there are sometimes very "long
tails" in decommissioning - the last 4 hours of a node decommissioning might be due to a handful
of stuck or slow blocks.  It drives our admins nuts that they don't know if things are 50%
done or 99.999% done (and should just pull the plug).
