----------------------------------------
Summary: Separate MapredWork into MapWork and ReduceWork
Key: HIVE-4825
URL: https://issues.apache.org/jira/browse/HIVE-4825
Project: Hive
Issue Type: Bug
Reporter: Gunther Hagleitner
Assignee: Gunther Hagleitner
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.
