Vijay updated CASSANDRA-3577:
-----------------------------
Attachment: (was: 0001-removing-mutation-MultiDC-optimization.patch)
> TimeoutException When using QuorumEach or ALL consistency on Multi-DC
> ---------------------------------------------------------------------
>
> Key: CASSANDRA-3577
> URL: https://issues.apache.org/jira/browse/CASSANDRA-3577
> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Affects Versions: 0.8.8
> Environment: JVM
> Reporter: Vijay
> Assignee: Vijay
> Fix For: 0.8.9
>
> Attachments: 0001-Mutation-Optimization-for-MultiDC.patch,
> 0001-removing-mutation-MultiDC-optimization.patch, 3577.txt
>
>
> Currently we have
> 1) StorageProxy.sendMessages() sending messages to the first node in the
> other DC...
> 2) A node in the other DC will remove the ForwardHeader and sendRR (Adding a
> MessageID to the Queue).
> 3) The receiving node receives the mutation, updates and sends the response
> to the Original Co-ordinator.
> 4) Co-Ordinator now checks for the MessageID (which it never had)
> All the Quorum_Each updates fail in the co-ordinator, this issue started
> showing up after CASSANDRA-3472 the code was introduced in CASSANDRA-2138 .
> Simple Fix is to remove the optimization in 0.8 and fix it in 1.x because it
> seems to me like it needs a change to the Message service version.
> Possible Solution: We might want send the message ID's to be used by the all
> the nodes in other DC (Which is currently generated by the node which
> receives the Forward request see: (2) ).
