[jira] [Commented] (MAPREDUCE-5481) Uber job reducers hang waiting to shuffle map outputs

    [ https://issues.apache.org/jira/browse/MAPREDUCE-5481?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13811406#comment-13811406 ] 

Xuan Gong commented on MAPREDUCE-5481:
--------------------------------------

Yes,  It is not only broke the TestUberAM. Under current trunk version, we can not even run the applications under the Uber mode.

> 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
