> 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
> This is caused by changes made in MAPREDUCE-434 breaking Uber AMs. The
> easiest fix is to make similar changes in Uber AMs to those in MAPREDUCE-434
> to allow multiple reducers.
