mmh, jenkings come back while I was writing my prev comment. But I believe jenkins is not testing MR, can somebody verify running {{mvn clean test -Dtest=TestMRJobs}}?

> 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...
