> As Rumen gets all the config properties into the trace file now(after
> MAPREDUCE-2153), Gridmix can set some of the important job-specific config
> properties obtained from trace to the simulated jobs. This imply that with
> same amount of input/output data for mapTask/reduceTask, the behavior of
> different other things like number of spills, sizes of spills, number of
> intermediate merges, etc would be similar to those were seen in original
> job(s).
