Subject [jira] [Commented] (HDFS-3980) NPE in HttpURLConnection.java while starting SecondaryNameNode.
Date Thu, 18 Oct 2012 06:04:03 GMT

    [ https://issues.apache.org/jira/browse/HDFS-3980?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13478710#comment-13478710

Aaron T. Myers commented on HDFS-3980:

Hi Brahma, that keytab config looks fine. Regarding the new stack trace you included above,
my guess would be that you've misconfigured the expected principal name of the NN.

At this point I think we should perhaps close this JIRA as invalid, and move this conversation
to user@hadoop.apache.org. I don't think this is an actual bug, but rather a misconfiguration
of some sort. What do you think, Brahma? We could certainly reopen this JIRA if it proves
to be an actual bug.
