Ryan King commented on CASSANDRA-957:
-------------------------------------

It would be easier if a node could start without joining the ring: CASSANDRA-526.

> Replacing a dead node with a new one is a common operation, but "nodetool removetoken"
followed by bootstrap is inefficient (re-replicating data first to the remaining nodes, then
to the new one) and manually bootstrapping to a token "just less than" the old one's, followed
by "nodetool removetoken" is slightly painful and prone to manual errors.
> First question: how would you expose this in our tool ecosystem?  It needs to be a startup-time
option to the new node, so it can't be nodetool, and messing with the config xml definitely
takes the "convenience" out.  A one-off -DreplaceToken=XXY argument?
