Brandon Williams commented on CASSANDRA-4047:
---------------------------------------------
The tricky part is, who stores the hint? Since it's a non-member doing the
streaming... I guess it could just choose some other target at random, but by
the time it does that the sstable might already be compacted away.

>
> With the introduction of the BulkOutputFormat, there may be cases where
> someone would like to tolerate node failures and have the job complete, but
> afterwards since we streamed they have to repair or rely on read repair. We
> don't currently have any way of hinting streams, but a node could take a
> snapshot before acknowledging the stream session, then remember to send the
> files in the snapshot to the unavailable nodes when they come back up. This
> isn't quite ideal since of course the node may have compacted these files,
> however it's much simpler than any sort of key tracking at this scale.
