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.
> MR is broken when security is off

> Key: HADOOP-8725
> URL: https://issues.apache.org/jira/browse/HADOOP-8725
> Project: Hadoop Common
> Issue Type: Bug
> Components: security
> Affects Versions: 0.23.3, 2.1.0-alpha, 3.0.0
> Reporter: Daryn Sharp

> 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...
