nodetool decommission

Deactivates a node by streaming its data to another node.

Causes a live node to decommission itself, streaming its data to the next node on the ring. See Decommissioning a datacenter, Removing a node, and Adding a node and then decommissioning the old node.

Tip: Use nodetool nodetool netstats to monitor the progress.

Note: Decommission does not shutdown the node, shutdown the node after decommission has completed.
