Jonathan Ellis commented on CASSANDRA-5186:
-------------------------------------------
If you've done concurrent schema changes such that two CFs got the same ID on
different machines you're SOL on any version. You'll need to blow away the
schema and recreate it. (1.2 should avoid getting into this situation in the
first place, but upgrading won't fix it once you're already there.)
