I'm using a thrift client and my Cassandra Partitioner is ByteOrderedPartitioner. I generate a key to force to store an item in a specific machine. But, this key comes different on Cassandra Server. For example, if my ByteBuffer key is [*98, 99, 100, 49, 57, 50, 53, 55, 98, 56, 49, 55, 100, 52, 52, 52, 52, 49, 98, 51, 53, 97, 98, 55, 56, 53, 52, 97, 51, 56, 97, 101, 101, 49*], this key comes on Cassandra with this value:

I discovered this debugging the StorageProxy class on Cassandra. *Why this happen?* I have to solve this problem, because when the key is different, the item is stored on a differente machine. -- Atenciosamente, Sávio S.
