                 Key: CASSANDRA-3598
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-3598
             Project: Cassandra
          Issue Type: Bug
          Components: Core
    Affects Versions: 0.8.8
            Reporter: Vijay
            Assignee: Vijay
            Priority: Minor
             Fix For: 0.8.9, 1.1


Looks like we send requests to all the nodes provided by 
StorageService.instance.getLiveNaturalEndpoints(keyspace, range.right);
We dont filter it based on blockedFor (Consistency levels).

In a multi DC setup this will cause unnecessary load on the other DC. And even 
within a DC we might query more nodes than needed.
