> cassandra-stress: No way to pass in data center hint for

> Key: CASSANDRA-8313
> URL: https://issues.apache.org/jira/browse/CASSANDRA-8313
> Project: Cassandra
> Issue Type: Improvement
> Components: Tools
> Reporter: Bob Nilsen
>
> 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?
