removing a node

[Sasha Dolgy <sd...@gmail.com>]

Hi there,

Wanted to clarify with anyone ... re:
http://wiki.apache.org/cassandra/Operations#Removing_nodes_entirely

You can take a node out of the cluster with nodetool decommission to a live
node, or nodetool removetoken (to any other machine) to remove a dead one.
This will assign the ranges the old node was responsible for to other nodes,
and replicate the appropriate data there. If decommission is used, the data
will stream from the decommissioned node. If removetoken is used, the data
will stream from the remaining replicas.


   - If the node is alive and functional, the command to be run from that
   node is:  nodetool decommission
   - If the node is dead, the command to be run from another node (or all
   other nodes) is:  nodetool removetoken <token>


-sd

yes.
dead normally means machine cannot be started.
