> createTable(HTableDescriptor desc, byte [] startKey, byte [] endKey, int numRegions)
(line #370) dictates that you must specify a minimum of three regions, however is not able
to handle being fed a value three. This is a result of line #379 where it attempts to create
the key splits, and calls Bytes.Split with a value of 0 for the third parameter. createTable
should instead just create a byte[][] with the startKey and endKey in this scenario.
