Daryn Sharp updated HADOOP-8725:
--------------------------------

    Attachment: HADOOP-8725.patch

I'm not sure how to easily write a test since there's not a supported way to set envs in java.
 Well, that's non-extremely-dirty-and-hacky by using reflection to bypass the immutable map.

> HADOOP-8225 broke MR when security is off.  MR was changed to stop re-reading the credentials
that UGI had already read, and to stop putting those tokens back into the UGI where they already
were.  UGI only reads a credentials file when security is enabled, but MR uses tokens (ie.
job token) even when security is disabled...
