Subject [jira] Commented: (HADOOP-5599) Unable to run jobs when all the nodes in rack are down
Date Mon, 06 Apr 2009 23:44:13 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-5599?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12696299#action_12696299
] 

Owen O'Malley commented on HADOOP-5599:
---------------------------------------

Did you have the topology defined? If not, there is nothing DFS can do. If so, the question
becomes why blocks ended up with all the replicas on one rack.
