Mck SembWever commented on CASSANDRA-2388:
------------------------------------------
This does happen already (i've seen it while testing initial patches that were
no good).
Problem is that the TT is blacklisted, reducing hadoop's throughput for all
jobs running.
I bet too that a fallback to a replica is faster than a fallback to another
TT. For example a c* node may die in the middle of a TT...
> ColumnFamilyRecordReader fails for a given split because a host is down, even
> if records could reasonably be read from other replica.
