> The test org.apache.cassandra.distributed.test.DistributedReadWritePathTest#failingReadRepairTest
makes a few assumptions which are not valid at the moment.
> 1) the write to node 1 and 2 have the same digest (they don’t, this is caused by the
timestamp being different)
> 2) node 3 will participate with the read; it won’t give the fact that org.apache.cassandra.locator.ReplicaPlans#contactForRead
will speculate the first 2 nodes always, so node 3 won’t get involved with the repair
> 3) node 3 will attempt to get repaired (it won’t because its never looked at)
