Ted Yu commented on HBASE-2473:
-------------------------------

In HBaseAdmin.createTable(), the following should be used:
    if (numRegions < 4) {
      throw new IllegalArgumentException("Must create at least four regions");
    } else if(Bytes.compareTo(startKey, endKey) >= 0) {
because Bytes.split(startKey, endKey, numRegions - 3) call cannot accept last parameter being 0.
