Mapping between Gridmix jobs and the corresponding original MR jobs is needed
-----------------------------------------------------------------------------

                 Key: MAPREDUCE-2137
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-2137
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: contrib/gridmix
    Affects Versions: 0.22.0
            Reporter: Ravi Gummadi
            Assignee: Ravi Gummadi
             Fix For: 0.22.0


Consider a trace file "trace1" obtained by running Rumen on a set of MR jobs' history logs.
When gridmix runs simulated jobs from "trace1", it may skip some of the jobs from the trace
file for some reason like out-of-order-jobs. Now use Rumen to generate trace2 from the history
logs of gridmix's simulated jobs.
Now, to compare and analyze the gridmix's simulated jobs with original MR jobs, we need a
mapping between them.
