JobControl.java should expose jobs as Lists rather than ArrayLists
------------------------------------------------------------------

                 Key: HADOOP-2268
                 URL: https://issues.apache.org/jira/browse/HADOOP-2268
             Project: Hadoop
          Issue Type: Improvement
          Components: mapred
    Affects Versions: 0.15.0
            Reporter: Adrian Woodhead
            Assignee: Adrian Woodhead
            Priority: Minor
             Fix For: 0.16.0


See HADOOP-2202 for background on this issue. Arun C. Murthy agrees that when possible it
is preferable to program against the interface rather than a concrete implementation (more
flexible, allows for changes of the implementation in future etc.) JobControl currently exposes
running, waiting, ready, successful and dependent jobs as ArrayList rather than List. I propose
to change this to List.

I will code up a patch for this.
