             Summary: cassandra-stress: No way to pass in data center hint for DCAwareRoundRobinPolicy
                 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?
