> When using cassandra-stress in a multiple datacenter configuration, we need to be able to behave like the applications do and send traffic to nodes co-located in the same data center.
> I can't for the life of me figure out how to pass in such a hint into the new cassandra-stress.
> And passing in a local node into "-node" doesn't help.  Apparently, cassandra-stress will *guess* the data center based on the order of the list that it receives from the cluster.
> In my case, it seems to always pick 'DC2', no matter what I do.
> INFO  22:17:06 Using data-center name 'DC2' for DCAwareRoundRobinPolicy (if this is incorrect, please provide the correct datacenter name with DCAwareRoundRobinPolicy constructor)
> Could someone please add the ability to configure the DCAwareRoundRobinPolicy with a data center hint?
