Aaron T. Myers commented on HDFS-3444:
--------------------------------------
No tests are included since this patch requires krb infrastructure to test per
the previous comment.
I'm pretty confident that the test failure is unrelated. It's in a completely
separate part of the code, and I just looped it 10 times on my laptop with no
failures.
