Sandy Ryza updated MAPREDUCE-5481:
----------------------------------
Description:
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.
