Attachment: CASSANDRA-242_part-2.diff
CASSANDRA-242_part-1.diff
The latest versions should get all of the coding style fixes, and include a
boolean preservesOrder flag for IPartitioners.

> Two tickets currently depend on being able to deterministically split a Range
> object into two "even" Ranges.
> This can be accomplished with RandomPartitioner/BigIntegerToken by taking the
> average of the tokens, but the OrderPreservingPartitioner/StringToken
> implementation uses a Java Collator to define the sort order of Tokens, which
> means that they are not necessarily sorted in byte/char order.
> Collator.getCollationKey(String).toByteArray() gets you a sortable byte
> array, but there is no publicly accessible API for converting a similar byte
> array back into a String.
