paul cannon commented on CASSANDRA-2496:
----------------------------------------
Ok, nodes do indeed infinitely retry the replication confirmation in some
cases, but it appears it's not just when the former removal coordinator has
restarted in the interim- it seems to be when the removetoken is reissued to
another, new removal coordinator. In this case, I get this traceback every 10
seconds:

I'll look into this.
Second, it seems that moving/joining nodes can take over the removed token
fine, once the removetoken is complete. I haven't tried having a node take over
the removed token while the removal is ongoing- I assume we can just document
that that probably isn't a great idea?
