Benedict commented on CASSANDRA-8778:
-------------------------------------
OK, I'm confused. [~jbellis] could you confirm what the aim is for this wrt
2.0? Sounds like this really is 2.1+ (though no major harm having it split out
as a ticket)

> Key: CASSANDRA-8778
> URL: https://issues.apache.org/jira/browse/CASSANDRA-8778
> Project: Cassandra
> Issue Type: Bug
> Reporter: Jeff Jirsa
> Assignee: Jeff Jirsa
> Priority: Trivial
> Attachments: cassandra-8778.diff, cassandra-8778.patch

>
> ChecksumWriter append() calculates the checksum of a buffer, then also writes
> that checksum as an int into the provided DataOutput. The final call to
> writeFullChecksum will have the checksum of all of the buffers, but none of
> the intermediate int checksums.
> This issue was discovered (and a fix proposed) in #5791 - if the patch for
> #5791 is not accepted, some fix for
> src/java/org/apache/cassandra/io/util/DataIntegrityMetadata.java should be
> applied.
