> HBaseAdmin.createTable() java doc says
> public void createTable(HTableDescriptor desc,
>                         byte[][] splitKeys)
>                  throws IOException
> Creates a new table with an initial set of empty regions defined by the specified split keys. The total number of regions created will be the number of split keys plus one (the first region has a null start key and the last region has a null end key). Synchronous operation.
> If we specify null values for first region start key and last region end key, geting NullPointerException as Arrays.sort compares each element.
> I guess the documentation should not talk about null values and explain about splitKeys[][] length as n-1, where n is number of regions.
> splitKeys[][] would look like
> splitKeys[0] = "key value 1"
> ..
> splitKeys[n-1] = "key value n-1"
