Hudson commented on MAPREDUCE-3280:
-----------------------------------

Integrated in Hadoop-Hdfs-trunk-Commit #1336 (See [https://builds.apache.org/job/Hadoop-Hdfs-trunk-Commit/1336/])
    MAPREDUCE-3280. Removed the unnecessary job user-name configuration in mapred-site.xml. (vinodkv)

> MR AM reads the value for mapreduce.job.user.name from the configuration in several places. It should instead get the app-submitter name from the RM.
> Once that is done, we can remove the default value for mapreduce.job.user.name from mapred-default.xml
