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