[jira] [Created] (CASSANDRA-6448) Give option to stream just primary replica via sstableloader

Adam Hattrell created CASSANDRA-6448:
----------------------------------------

             Summary: Give option to stream just primary replica via sstableloader
                 Key: CASSANDRA-6448
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-6448
             Project: Cassandra
          Issue Type: Improvement
          Components: Tools
            Reporter: Adam Hattrell
            Priority: Minor


A fair number of people use sstableloader to migrate data between clusters.

Without vnodes it's usually possible to pick a set of nodes that ensure that you don't stream multiple copies of your sstables (where RF > 1) - but with vnodes that seems to be much harder.

Would it be feasible to get sstableloader only to stream data from primary replicas?
