Subject [jira] [Commented] (HDFS-6312) WebHdfs HA failover is broken on secure clusters
Date Fri, 02 May 2014 14:13:15 GMT

    [ https://issues.apache.org/jira/browse/HDFS-6312?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13987725#comment-13987725

Daryn Sharp commented on HDFS-6312:

Yes, of course on the tests. :)  I don't enjoy being the test subject for security changes
with no code coverage...  I may fix this as part of a later change.

>                 URL: https://issues.apache.org/jira/browse/HDFS-6312
>             Project: Hadoop HDFS
>          Issue Type: Bug
>          Components: webhdfs
>    Affects Versions: 3.0.0, 2.4.0
>            Reporter: Daryn Sharp
>            Assignee: Daryn Sharp
>            Priority: Blocker
> When webhdfs does a failover, it blanks out the delegation token.  This will cause subsequent
operations against the other NN to acquire a new token.  Tasks cannot acquire a token (no
kerberos credentials) so jobs will fail.
