Riak 1.3 YCSB Read Time Out

Hello Veronika -

  We're actively working on the YCSB project located at [0]. It should work
fine with Riak 1.4. Since the existing implementation of YCSB is a
work-in-progress, you can't trust any results it gives you until we get it
merged upstream with the official YCSB repo. I'm not sure what's causing
the "Read timed Out" exception, can you provide any logs?

Cheers -
Dave
