Subject [jira] [Commented] (HDFS-3873) Hftp assumes security is disabled if token fetch fails
Date Fri, 31 Aug 2012 21:19:07 GMT

    [ https://issues.apache.org/jira/browse/HDFS-3873?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13446386#comment-13446386

Robert Joseph Evans commented on HDFS-3873:
-------------------------------------------

It looks good to me.  I am not really an expert on HFTP, but this is a simple enough change
that I feel OK to give it a +1, but please use your discretion before checking it in.

I am not sure why Jenkins ran the tests again and they failed, but when I run them with your
patch they pass. except for TestHftpDelegationToken which is a known issue.

> Hftp ignores all exceptions generated while trying to get a token, based on the assumption
that it means security is disabled.  Debugging problems is excruciatingly difficult when security
is enabled but something goes wrong.  Job submissions succeed, but tasks fail because the
NN rejects the user as unauthenticated.
