You may do, if a node is no longer a replica for a token range. Which would be
similar to reducing the RF.
nodetool cleanup is the thing to run after you have repaired to remove data a
node should no longer have.

Hi Aaron - Yes, I've read the part about changing the replication factor on a
running cluster. I've even done it without a problem. My real point of my

See the section on Replication here
http://wiki.apache.org/cassandra/Operations#Replication It talks about how to
change the RF and then says you can do the same when change the placement
strategy.
It can be done, but is a little messy.
Depending on your setup it may also be possible to copy
From my understanding of replica copies, cassandra picks which nodes to
replicate the data based on replication strategy, and those same "replica
partner" nodes are always used according to token ring distribution.
If you change the replication strategy, does cassandra pick new nodes to
repl
