Subject [jira] [Commented] (MAPREDUCE-50) NPE in heartbeat when the configured topology script doesn't exist
Date Thu, 09 Feb 2012 17:40:00 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-50?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13204676#comment-13204676
] 

Steve Loughran commented on MAPREDUCE-50:
-----------------------------------------

Note that the {{DNSToSwitchMapping}} says nothing about returning null on any problem; the
behaviour of the implementation is not consistent with the javadocs
