Sylvain Lebresne commented on CASSANDRA-2606:
---------------------------------------------
Wait a minute ... that doesn't really work :(
Or more precisely, repairing a given range on a node N only make sure that N
has this range up to date. The other replica for this range may not be fully up
to date on that range. Meaning that running repair on the primary range for all
node won't result in a fully repaired ring.
Actually I think the right fix would be to make it so that repairing a range
really repair this range on all the replica for this range, independently of
which node we connected to to start the repair. I've created CASSANDRA-2610 for
that. So sorry about that but I think we should wait on that last ticket before
committing this.

> CASSANDRA-2324 introduces the ability to do a repair only on a given range.
> This ticket proposes to add a nodetool repairPrimaryRange to trigger the
> repair of only the primary range of a node. This allows to repair a full
> cluster without any work duplication (or at least make it much simpler). This
> also introdude a global_repair command to clustertool to trigger the primary
> range repair on each node of the cluster one after another (we could do all
> in parallel, but that's probably not nice on the cluster).
