That doc is incomplete, IMO. It (and the doc for adding a node) should
contain an instruction to run repair. Rebuild, like bootstrap, streams from
only one replica. Due to CASSANDRA-2434 [1], if you do not repair after
rebuild you may be missing data in your new DC when read at QUORUM_LOCAL. I
have bcc:ed docs@datastax for their information. :)
