> Hadoop need a tool for stressing JobTracker and NameNode. Mumak introduced a
> simulated JobTracker, whose behavior doesn't exactly like that of the real
> JobTracker. Even more, mumak can't simulate a large cluster with quite a lot
> of jobs run on it. On the other hand, Gridmix v3 need hundreds of physical
> nodes to replay job stories.
> You can think this tool a complementation of mumak and gridmix v3. We
> successfully used this tool to simulate a 12000 nodes cluster through 4 real
> machines.
> I've talk to Hong Tang and Scott Chen offline, they suggested me contributing
> this tool to the hadoop community.
