Brandon Williams commented on CASSANDRA-2388:
---------------------------------------------

I'm not sure special casing NoRouteToHostException to be blacklisted is the best thing to do.  I don't think connections are being setup so often that maintaining a blacklist for any reason is needed.

> ColumnFamilyRecordReader only tries the first location for a given split. We should try multiple locations for a given split.
