Subject [jira] [Commented] (HDFS-7411) Refactor and improve decommissioning logic into DecommissionManager
Date Mon, 02 Feb 2015 22:08:34 GMT

    [ https://issues.apache.org/jira/browse/HDFS-7411?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14302030#comment-14302030
] 

Tsz Wo Nicholas Sze commented on HDFS-7411:
-------------------------------------------

I also like to get this work here committed faster.  So, I suggest
# Create another JIRA for a pure code refactoring.  Move all the existing code to DecommissionManager.
 No logic change.
# Change the patch here to add the new decommission code but NOT removing the existing code
so that it uses the old code if the old conf is set and the new code if new conf is set.

Sound good?
