> I think that it is silly to have tools parsing the strings that the framework 
> builds for task ids. I propose:
> class JobId implements Writable {
>    public int getJobId() {...}
> }
> class TaskId implements Writable {
>   public JobId getJobId(); 
>   public boolean isMap() { ... }
>   public int getTaskId() { ... }
> }
> class TaskAttemptId implements Writable {
>   public TaskId getTaskId();
>   public int getAttemptId();
> }
> each of the classes will have a toString() method that generates the current 
> string.
