Subject Re: Upgrade path to 2.0
Date Tue, 13 Aug 2013 21:58:25 GMT
Thanks, I won't be upgrading to 2.0 any time soon but I would prefer
not to have to do a minor 1.2.8->1.2.9 upgrade before I do down the
road.

If I'm reading this right, it seems CASSANDRA-5695 only bumps the
upgrade path to 1.2.7. And is CASSANDRA-5845 still a concern if we
don't make any schema changes while the cluster is in a split version
state?
