> Talked with Lars about how we can make it easier for users to run the YCSB benchmarks against HBase & get realistic results.  Currently, HBase is optimized for the random/uniform read/write case, which is the YCSB load.  The initial reason why we perform bad when users test against us is because they do not presplit regions & have the split ratio really low.  We need a one-line way for a user to create a table that is pre-split to 200 regions (or some decent number) by default & disable splitting.  Realistically, this is how a uniform load cluster should scale, so it's not a hack.  This will also give us a good use case to point to for how users should pre-split regions.
