>          Issue Type: Bug
>            Reporter: Hong Tang
> The first release of Mumak (MAPREDUCE-728) introduces some coupling between the core
mapred code with Mumak code. Specifically, New constructors are added to JobTracker and JobInProgress
to allow simulator to subclass and alter JT/JIP behavior. This could be a code maintenance
overhead when new changes have to be ported to either the added constructors or the simulation
> It would be nice to refactor the constructors of JobTracker and JobInProgress to avoid
as much code duplication as possible.
