Bikas Saha commented on TEZ-1062:
---------------------------------
We should first go through all outputs to check if they are MROutput and if
they need commit. Collect these. If non-empty collection ask for commit
permission. After that call commit on all collected outputs. If any commit
throw exception then call abort on all collected outputs.
We can create a SimpleProcessor in tez-runtime-library and
SimpleProcessorWithMRCommit that derives from SimpleProcessor() in
tez-mapreduce project.
> 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.
