This is not localized to just TestUberAM, as all uber jobs with reducers will currently hang like this.  This appears to have been broken when MAPREDUCE-434 was committed, since it changed the way reducers locate map outputs when not running via normal containers.

Updating the summary to better reflect the issue.

> TestUberAM has been timing out on trunk for some time now and surefire then fails the build.  I'm not able to reproduce it locally, but the Jenkins builds have been seeing it fairly consistently.  See https://builds.apache.org/job/Hadoop-Mapreduce-trunk/1529/console
