[dtest|http://cassci.datastax.com/job/yukim-10288-2.1-dtest/].
I added live node check before sending prepare and anticompaction message.
bq. There should probably be a timeout-and-abort path as well.
There are timeout actually, but it's set to long (1 hour / 1 day).
I feel the need to periodically ping repair status of all replica, since
timeout is not suitable for every environment, and still message can be lost.
I will create the ticket for this.

> So with a cluster of 3 nodes and a RF=3 for my keyspace, I tried to repair my
> data with a single node down. I got 3 different behaviours with different C*
> versions. With:
> cassandra-2.1: it fails saying a node is down. (acceptable)
> cassandra-2.2: it hangs forever (???)
> cassandra-3.0: it completes successfully
> What is the correct behaviour of this repair use case? Obviously,
> cassandra-2.2 has to be fixed, too.
> Here are the result logs when testing:
> cassandra-2.1
> {code}
