> 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.
