Vijay commented on CASSANDRA-957:
---------------------------------
I'm also unsure about the reasoning behind the last patch. Why increase the
initial sleep in joinTokenRing?
-- Ring delay + extra time so we can check if there is any live server before
actually replacing the node.
> convenience workflow for replacing dead node

> 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?
