Rumen is used to generate a trace file from the job history files on a pre-existing cluster. This trace file can then be fed into gridmix (for example) to "simulate" the same workload on that cluster again (or another cluster for that matter). https://hadoop.apache.org/docs/stable/rumen.html. Rumen also allows you to specify a scaling factor, so if you were able to get a trace for a much bigger cluster, you could scale it down to run on a much smaller cluster.
I'm afraid I'm not familiar with Mumak.
You might also be interested in this JIRA: https://issues.apache.org/jira/browse/YARN-1021 . Unfortunately, it hasn't been checked into the repository yet, so you will have to apply the patch yourself.

Subject: Doubt regarding hadoop simulator
I am searching for MapReduce simulator in online.
I heared some names like *Rumen and Mumak.*
But unable to understand thease simulator.
I have modified some changes on Fair scheduling.
i want to run the simulation for same workload for original Fair scheduler
and modified fair scheduler. And see the difference in the response time,
fairness, locality and network traffic.
I dont have real enviornment to run my experiments.
Please help me in this regard. Is is possible with rumen and mumak?
Is there any other simulater available?
Thanks in Advance...
