Generalize mapred.child.ulimit so as to help setting up other limits.

                 Key: HADOOP-3974
                 URL: https://issues.apache.org/jira/browse/HADOOP-3974
             Project: Hadoop Core
          Issue Type: Bug
          Components: mapred
            Reporter: Vinod Kumar Vavilapalli


Currently mapred.child.ulimit cannot be used for anything other than for setting virtual limits. It is hardcoded to set virtual mem limits (ulimit -v) only. This should be changed so that other limits like open file descriptors, max user processes etc can be set.
