+1 on what Alain said, but I do think if you are high enough on a 2.1.x (will look later) version you don't need to follow the documentation. It is outdated. Run a full repair, the you can start incremental repairs since the SSTables will have the metadata on them about the last repair.
Wait someone to confirm this/or confirm the docs are correct.
