Jonathan Ellis commented on CASSANDRA-2606:
-------------------------------------------

+1

nit: should we call it the "partitioner range" or something else b/s "primary," which has connotations that we'd prefer to avoid?

> 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).
