We have a cassandra cluster of 6 nodes with RF=3D3, read-repair= enabled, hinted handoff disabled, WRITE with QUORUM, READ with ONE.
we = want to rely on read-repair totally for node failure, as returning inconsis= tent result temporarily is ok for us.

If a node is temporarily dead and returneded to the cluster later, ever= ything seems fine.
If a node is damaged and a new node with different IP= is added, can I just assign dead node's initialToken to him and have r= ead-repair handle everything?

I have read the wiki: http://www.riptano.com/docs/0.6.5/operations/clustering<= /a> .
But in order to keep it simple, I don't want to use autoboots= trap, noderepair, removetoken, etc
