      Description

      I've run wordcount example on branch-2 and trunk. I've set yarn.nodemanager.resource.memory-mb to 1G and yarn.app.mapreduce.am.resource.mb to 1.5G. Therefore, resourcemanager is to assign a 2G AM container for AM. However, the nodemanager doesn't have enough memory to assign the container. The problem is that the assignment operation will be repeated infinitely, if the assignment cannot be accomplished. Logs follow.
