HBase is primarily a storage system, not a computation system, so there are
no CPU-bound workloads as such. I suppose you can try to artificially
increase CPU load on the RegionServers by using expensive
compressions/encodings. Your other option would be to run a MR job on the
same cluster -- those processes will compete with RS's for resources.
Could you provide a little more context for your project?
