> 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.
