Jonathan Ellis commented on CASSANDRA-1459:
-------------------------------------------

shouldHint can be simplified to         return Gossiper.instance.getEndpointDowntime(ep) <=
maxHintWindow;

+1 w/ that change

> If there is an extended downtime of a node, allow Hinted Handoff to be disabled specifically
for that node rather than having to decommission it. 
> <benblack> If a node will be down for an extended period, it would be useful to
be able to disable HH for it until it returns, without having to reconfigure and restart nodes.
