> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Affects Versions: 0.7 beta 2
> Environment: Linux 2.6.18
> JVM 6b11
> Reporter: ivan

>
> We experience TSocket: timed out reading expections randomly using DCQUORUM.
> In log we see that sometimes responses are not sent to client.
> Read requests are sent to all cluster members instead of member of a DC.
> Attached patch adds a new commandType argument to *NaturalEndpoint methods.
> It's needed to separate endpoint list for read and write commands, so for
> read requests endpoint list will contain servers in local DC.
> For write requests endpoints provided in all DCs.
> In DatacenterQuorumResponseHandler.response signal is not sent in case of a
> version mismatch.
> (In this case we experienced timed out reading exceptions.)
