our YCSB Fork

Dear YCSB Tream,

We have been doing plenty of work around the YCSB last year. When reviewing the code we have found it does not fit benchmarking in-memory products since it wasn’t accurate enough and was not designed for high concurrency testing , especially when used with local / near cache testing. You can find our fork here:
https://github.com/javamc/YCSB

Beyond updating large portions of the YCSB core , we have implementation for GigaSpaces and Gemfire. See exact info how to run the benchmark for these here:
https://github.com/javamc/YCSB/tree/master/gigaspaces

We had several requests having this code merged with the official TCSB branch hence the pull request. We would appreciate having it merged.

Thanks
