Hudson commented on MAPREDUCE-2137:
-----------------------------------

Integrated in Hadoop-Mapreduce-trunk-Commit #702 (See [https://builds.apache.org/hudson/job/Hadoop-Mapreduce-trunk-Commit/702/])
    MAPREDUCE-2137. Provide mapping between jobs of trace file and the corresponding simulated cluster's jobs in Gridmix.

> 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.
