Brandon Williams commented on CASSANDRA-4559:
---------------------------------------------
bq. Updated patch fixes that, but there's still something wrong, however nodes
at least stream out now.
I take it back that something is still wrong, replicas are all going to right
places now. The remaining problems that I see are the aforementioned NPE (very
rare) and sometimes I see nodes incorrectly fall back to generation comparison
on token conflicts instead of relocating, leading to different views of the
ring on different nodes. I'm not really sure what is causing either of these
yet.
