@sergeytsivin thanks for the pull request!
We updated to the MongoDB driver version you PRed, https://github.com/brianfrankcooper/YCSB/blob/master/pom.xml#L52, so that looks good.
Could you update the mongodb README file to reflect the confiugration changes?
obviated by #180. please reopen if there's a gap in the functionality it provides.
