Subject [jira] [Resolved] (HDFS-2987) DNA_SHUTDOWN command is never sent by the NN
Date Sat, 18 Aug 2012 00:10:38 GMT

     [ https://issues.apache.org/jira/browse/HDFS-2987?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Suresh Srinivas resolved HDFS-2987.
-----------------------------------

    Resolution: Won't Fix

For now lets retain DNA_SHUTDOWN command. Reopen this bug if we really need to remove that
command or create a new jira.

has never been sent by the NN (it was introduced by HADOOP-641 in 0.8.0!)
