Jon Hermes commented on CASSANDRA-1553:
---------------------------------------

If desired, getOwnership() should probably be changed to calculateOwnership() 
on the MBean so that "Ownership" doesn't try to show up as an attribute on 
StorageService. :(

> warn of imbalanced ranges in nodetool ring

> I'd like to enhance nodetool ring to show the % of the token range that it is 
> responsible for according to the partitioner (that is, before considering 
> replication).  For RandomParitioner this is easy.  For OPP we can estimate 
> using describe_splits.  I'd also like to issue a warning if any node N has 
> more than 25% more of the ring than another node M.
> (The reason we need to use the range for this instead of load, is load may 
> include an arbitrary amount of data that no longer belongs to the node, 
> pending removal by cleanup.)
