This is great Matteo. We need this. Yeah, agree, this tool will have most
value if it puts nothing but a lone region (and WAL).
Few minors below:
Missing annotatations on audience.
Do you need these? IIRC, the default exists w/ need of definition:
{code}
+ public HLogPerformanceEvaluation() {
+ }
{code}
You do it in another place at least too.
No harm adding a bit of class doc on HLogPutBenchmark
You don't want to use a command parser?

Interesting tool.

I don't see where region is closed.
There should be some cleanup method after the benchmarking is completed.
