Attachment: HDFS-6312.attempted.patch
Hi Daryn,
Attached is a quick fix for this issue, I tried to write a testcase but was not
successful. However, I tested out the fix in a real cluster and I can see the
problem without the patch, and see the patch resolved the problem.
Would you please take a look to see if we can have this issue fixed first?
Thanks a lot!

> 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.
