> I've got two nodes with tokens 00000000 and 88888888. I add 16 rows in which are spread over them, then do a key range scan.
> I can scan part of the range successfully, but if I try to scan the entire range of keys (0-f) then I get unexpected results
> ./Cassandra-remote -h localhost:9160 get_key_range Keyspace1 Standard1 0 31 1000
> ['00', '01', '10', '11', '20', '21', '30', '31']
> ./Cassandra-remote -h localhost:9160 get_key_range Keyspace1 Standard1 3 81 1000
> ['30', '31', '40', '41', '50', '51', '60', '61', '70', '71', '80', '81']
>  ./Cassandra-remote -h localhost:9160 get_key_range Keyspace1 Standard1 7 b1 1000
> ['70', '71', '80', '81', '90', '91', 'a0', 'a1', 'b0', 'b1']
> ./Cassandra-remote -h localhost:9160 get_key_range Keyspace1 Standard1 a g 1000
> ['a0', 'a1', 'b0', 'b1', 'c0', 'c1', 'd0', 'd1', 'e0', 'e1', 'f0', 'f1']
> All of which returned as I expected.
> But when I range scan the whole lot (0-g) then I get:
> ./Cassandra-remote -h localhost:9160 get_key_range Keyspace1 Standard1 0 g 1000
> [ '00',
>   '90',
>   '91',
>   'a0',
>   'a1',
>   'b0',
>   'b1',
>   'c0',
>   'c1',
>   'd0',
>   'd1',
>   'e0',
>   'e1',
>   'f0',
>   'f1']
> Where have 01-81 gone?
> I'll attach the data loading script.
