             Summary: Repaired data tracking isn't working for range queries
                 Key: CASSANDRA-15019
             Project: Cassandra
          Issue Type: Bug
          Components: Consistency/Coordination, Consistency/Repair, Test/dtest
            Reporter: Sam Tunnicliffe
            Assignee: Sam Tunnicliffe
             Fix For: 4.0

CASSANDRA-14145 introduced optional tracking of the repaired dataset used to 
construct a read response. If enabled, each replica computes a digest for the 
repaired portion of the data, which the coordinator compares in order to detect 
divergence between replicas. This isn't working correctly for range reads, as 
the ReadCommand instance that the DataResolver is intialized with does not have 
the tracking flag set. This has been undetected up until now as the dtest which 
should verify itĀ also has a bug in that when the relevant range query is issued 
the test expectations are being incorrectly set.
