  === Replacing a Dead Node ===
  ==== For versions 1.2.0 and above ====
- Token replace (introduced in CASSANDRA-957) does not work in 1.2.0 and above 
and should not be used while replacing a dead node. When dealing with node 
failure, use `nodetool` with the `removetoken` argument to remove the dead node 
from the ring. Once that process is complete, then bootstrap the new node back 
into the cluster.
+ Token replace (introduced in CASSANDRA-957) does not work in 1.2.0 and above 
and should not be used while replacing a dead node. When dealing with node 
failure, use `nodetool` with the `removenode` argument to remove the dead node 
from the ring. Once that process is complete (it involves streaming data that 
node contained from other nodes so this process can take a while, use nodetool 
netstats to monitor the progress of the streaming operation on other nodes), 
then bootstrap the new rebuilt node back into the cluster.
  
  ==== For versions 1.1.11 and older ====
  Since Cassandra 1.0 we can replace a dead node with a new one using the 
property "cassandra.replace_token=<Token>", This property can be set using -D 
option while starting cassandra demon process.
