-------------------------------------------
I like where you're going here. Maybe split the DCs out even more explicitly?

> Project: Cassandra
> Issue Type: Improvement
> Components: Tools
> Reporter: Aaron Morton

> Fix For: 1.1.2

> see http://www.mail-archive.com/user@cassandra.apache.org/msg16375.html
> When a cluster the multiple rings approach to tokens the output from nodetool
> ring is incorrect.
> When it uses the interleaved token approach (e.g. dc1, dc2, dc1, dc2) it will
> be correct.
> It's a bit hacky but could we special case (RP) tokens that are off by 1 and
> calculate the ownership per dc ? I guess another approach would be to add
> some parameters so the partitioner can be told about the token assignment
> strategy.
