Sylvain Lebresne updated CASSANDRA-2290:
----------------------------------------
Description:
Repair don't cope well with dead/dying neighbors. There is 2 problems:
# Repair don't check if a node is dead before sending a TreeRequest; this is
easily fixable.
# If a neighbor dies mid-repair, the repair will also hang forever.
The second point is not easy to deal with. The best approach is probably
CASSANDRA-1740 however. That is, if we add a way to query the state of a
repair, and that this query correctly check all neighbors and also add a way to
cancel a repair, this would probably be enough.
Remaining Estimate: 1h
Original Estimate: 1h
> Repair hangs if one of the neighbor is dead
