Jonathan Ellis updated CASSANDRA-1481:
--------------------------------------

    Attachment: 1481-v2.txt

v2 eliminates the Properties field to emphasize that the hashmap is the source of truth, and simplifies parsing by using string.split (since parsing is now done only once, it's ok to be a bit less efficient).

> the Properties class extends Hashtable, which is ancient and synchronized.
> (this is not really a problem in 0.7, since snitch results are cached.)
