[Gridmix] Gridmix should faithfully emulate old and new mapred(uce) APIs
------------------------------------------------------------------------
Key: MAPREDUCE-2540
URL: https://issues.apache.org/jira/browse/MAPREDUCE-2540
Project: Hadoop Map/Reduce
Issue Type: Improvement
Components: contrib/gridmix
Reporter: Amar Kamat
Fix For: 0.23.0
Gridmix currently submits jobs to the simulated cluster using the new MapReduce API. Since
the old and new mapred(uce) APIs have different code paths, it would be useful if Gridmix
faithfully emulates this behavior. Information regarding whether the original job used old
or new API is captured in the job's configuration.
