Runtian Liu commented on CASSANDRA-17314:
-----------------------------------------
I think this is only broken in 3.0. The fix is mostly borrowed from 3.11/4.0
code. The bug in 3.0 is that when throwing error
[here|https://github.com/apache/cassandra/pull/1707/files#diff-34814e77850d8cdcae4e28d7edb14ae7a3052c2e28101ca7c347687fc427670aR122],
the checksum is not reset. We need to reset checksum every time we try to
compare. 3.11 and 4.0 has the function to calculate the checksum. Also, we need
to clear the buffer to make sure the reader doesn't see stale data. 4.0 has
similar code
