> 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.
