Subject Re: Do I have to use repair -inc with the option -par forcely?
Date Tue, 16 Feb 2016 15:39:57 GMT
+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outdated.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.
