Subject [jira] [Commented] (HDFS-7411) Refactor and improve decommissioning logic into DecommissionManager
Date Mon, 02 Feb 2015 23:26:36 GMT

    [ https://issues.apache.org/jira/browse/HDFS-7411?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14302316#comment-14302316
] 

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

> Because of this, I do not see any advantage to keeping this old code around. ...

Users are familiar with the existing behavior so that we have to keep the old code, deprecate
them first and then remove them later.  It is a standard procedure for changing the behavior
of a feature.  No?

> I still plan to commit tomorrow.

-1 on the patch.
