Hi Kudu!
The YCSB project is currently testing out release candidates for our 0.14.0 release. This release will contain an update to Kudu client libraries and some additional client-side configuration options. If anyone has a spare 30 or so minutes, we could use help testing out things so that the Kudu client can stay in our "tested in a release and supported" category. For details on what's involved in testing and where to get the release candidate, please see the following issue: https://github.com/brianfrankcooper/YCSB/issues/1117 - busbey
