Siddharth Seth commented on TEZ-1062:
-------------------------------------
Intermediate outputs don't need a commit. They always write to their own
specific paths - and if multiple attempts succeed (speculative), it should be
possible to pull data from any of the successful attempts.
> Create SimpleProcessor for processors that only need to implement the run
> method

> The SimpleProcessor could take care of all things like starting input,
> committing outputs. It would handle no events, since simple processors dont
> need to handle inputs. Thus the user would only need to implement their
> custom task logic in a new execute() method.
