Subject [Cassandra Wiki] Update of "Operations" by StuHood

Dear Wiki user,

The "Operations" page has been changed by StuHood.

--------------------------------------------------

  
  Cassandra is smart enough to transfer data from the nearest source node(s), if your !EndpointSnitch
is configured correctly.  So, the new node doesn't need to be in the same datacenter as the
primary replica for the Range it is bootstrapping into, as long as another replica is in the
datacenter with the new one.

  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.
  
  No data is removed automatically from the node being decommissioned, so if you want to put
the node back into service at a different token on the ring, it should be removed manually.
