Brandon Williams commented on CASSANDRA-2388:
---------------------------------------------
Unfortunately, I thought of another problem here. If we go over the entire
replica set, we're potentially going outside of the DC, which is bad since a
lot of installations have a DC dedicated to analytics so it doesn't affect
their app. It seems that the local address is preferred though, are your task
trackers not on the same machines as Cassandra?
> ColumnFamilyRecordReader fails for a given split because a host is down, even
> if records could reasonably be read from other replica.
