Taras Puchko commented on CASSANDRA-2867:
-----------------------------------------
This problem is not related to migration, just 0.8.1 - 0.8.2 cannot start when
there is a super column family with different comparators for supercolumns and
metadata.
> Starting 0.8.1 after upgrade from 0.7.6-2 fails

> It seems this has something to do with indexes, and I do have a CF with an
> index on it, but it is not used.
> I can try and remove the index with 0.7.x binaries, but I will wait a bit to
> see if anyone needs it to reproduce the bug.
