Bikas Saha commented on TEZ-1062:
---------------------------------
[~kamrul] This is motivated by the discussion we had on TEZ-700 about
simplifying most of the existing processors we currently have. We skipped that
in TEZ-700 but we can now base on TEZ-695 and create another abstract class
SimpleProcessor that provides impls for all base methods except for the run
method. We can use your suggestion of having simpleprocessor.run(Map<Inputs,
Outputs>) call input.start() and then call real.run(). Similar to what we did
for the initialize() method. This will really simplify writing simple
processors.
This wont work for Input/Output since they usually have to handle events
(unlike Processor). What do you think?
> 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.
