Benedict commented on CASSANDRA-6707:
-------------------------------------
bq. You are supposed to 'nodetool drain' before upgrading (or, at least I
always assumed so).
Even so, I don't think there's a good reason for this to fail - nothing has
changed in log replay. Seems like we should be resilient to this if possible.
I would guess it's because any schema upgrading hasn't happened before we
replay the CL, so we don't find the CFs the records are associated with, as I
can't see any other reason for this to go wrong.
