> Separate MapredWork into MapWork and ReduceWork

> Project: Hive
> Issue Type: Improvement
> Reporter: Gunther Hagleitner

> Priority: Minor
> Attachments: HIVE-4825.1.patch, HIVE-4825.2.code.patch,

> Right now all the information needed to run an MR job is captured in
> MapredWork. This class has aliases, tagging info, table descriptors etc.
> For Tez and MRR it will be useful to break this into map and reduce specific
> pieces. The separation is natural and I think has value in itself, it makes
> the code easier to understand. However, it will also allow us to reuse these
> abstractions in Tez where you'll have a graph of these instead of just 1M and
> 0-1R.
