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.
> Add to admin create table start and end key params and desired number of
> regions
