Ravi Prakash commented on MAPREDUCE-4134:
-----------------------------------------

Bobby's already pointed out in https://issues.apache.org/jira/browse/MAPREDUCE-4079?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13255804#comment-13255804
that

bq. The build errors are because HADOOP-8227 has not made it into the 3.0.0-SNAPSHOT release
of common yet. It should be in tomorrow and I will kick it again then.

> Courtesy Philip Su, we found that (mapred.child.ulimit, mapreduce.map.ulimit, mapreduce.reduce.ulimit)
were not being used at all. The configuration exists but is never used. Its also mentioned
in mapred-default.xml and templates/../mapred-site.xml . Also the method getUlimitMemoryCommand
in Shell.java is now useless and can be removed.
