Subject [jira] [Commented] (HDFS-7411) Refactor and improve decommissioning logic into DecommissionManager
Date Mon, 02 Feb 2015 20:32:36 GMT

    [ https://issues.apache.org/jira/browse/HDFS-7411?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14301870#comment-14301870
] 

Colin Patrick McCabe commented on HDFS-7411:
--------------------------------------------

Thanks for splitting off the logging changes, Andrew.

It's reasonable to keep backwards compatibility by supporting {{dfs.namenode.decommission.nodes.per.interval}}.
 I can see that you have done this in the latest patch.  Maybe eventually in Hadoop 3.0 we
can drop support for this parameter.

+1.
