-------------------------------------------
That was fixed in 1.2.5. CASSANDRA-5424
> "Primary range" repair still isn't quite NTS-aware

> Key: CASSANDRA-5608
> URL: https://issues.apache.org/jira/browse/CASSANDRA-5608
> Project: Cassandra
> Issue Type: Bug
> Components: Tools
> Affects Versions: 1.2.5
> Reporter: Jonathan Ellis
>
> Consider the case of a four node cluster, with nodes A and C in DC1, and
> nodes B and D in DC2. TokenMetadata will break this into ranges of (A-B],
> (B-C], (C-D], (D-A].
> If we have a single copy of a keyspace stored in DC1 only (none in DC2), then
> the current code correctly calculates that node A is responsible for ranges
> (C-D], (D-A].
> But, if we add a copy in DC2, then we only calculate (D-A] as primary range.
> This is a bug; we should not care what copies are in other datacenters, when
> computing what to repair in the local one.
