Jason Brown commented on CASSANDRA-14002:
-----------------------------------------
bq. we don't need to worry about the upgrade path here because streaming will
be broken between majors anyways
This is correct, but not because "streaming is broken between majors". There
are no guarantees that an un-upgraded node would be parse to read sstables
streamed to it from an upgrade node, as the sstable format may have changed (we
do not force/guarantee backward compatibility of the sstable format). Thus, we
don't support streaming between major versions (although there's nothing that
bluntly states this, at least as far as I've seen).
