Brandon Williams updated CASSANDRA-1617:
----------------------------------------
Attachment: 1617.txt
In CASSANDRA-1439, we changed the hint destinations from fixed-length encoding
to variable-length encoding (by converting UTF-8, to make OPP happy.) We
neglected to frame the message, however. Patch adds framing and fixes a debug
message that is broken.

> There might be a bug in hinted handoff?
> I have a cluster of 8, replication factor of 3, doing reads/writes with
> QUORUM.
> I have a single thread doing reads/writes of about 2kb across all nodes,
> running about 200hps.
> When I shut down one node, within a few seconds I start seeing some very big
> recent write latencies, 4-5 seconds.
> I looked at the system.log on the node with the adjacent token to the node
> that I shut down, and see a bad looking BufferUnderflowException:
