Aleksey Yeschenko commented on CASSANDRA-6707:
----------------------------------------------
bq. I would guess it's because any schema upgrading hasn't happened before we
replay the CL
Nope, most definitely not it (no breaking schema changes that could affect this
between 1.2 and 2.0).
The RowMutation serialization, however, has changed between VERSION_12 and
VERSION_20 (keyspace name present/absent). The commitlog is, and has always
been, implicitly versioned, even if the replay code itself hasn't changed.
