Robert Joseph Evans commented on HADOOP-10164:
----------------------------------------------

The test failure appears to be spurious.  The test failed for me 1 out of 4 runs. It is a multi-threaded test case that failed too. I will look into it a bit more and will file a JIRA about the test failure.

I did not include any new tests, because it is a really small re-factor and the existing tests should all pass.

> For storm I would love to let Hadoop initialize based off of credentials that were already populated in a Subject.  This is not currently possible because logging in a user always creates a new blank Subject.  This is to allow a user to be logged in based off a pre-existing subject through a new method.
