 Index Scan's will span across multiple DC's

 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, 1.0.6

 Attachments: 0001-super-simple-patch-3598.patch


 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.

Integrated in Cassandra-0.8 #414 (See 
[https://builds.apache.org/job/Cassandra-0.8/414/])
range and index scans now only send requests to enough replicas to satisfy 
requested CL + RR
