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.

Decommission puts a node in LEAVING state. The leaving node keeps its CQL port open and continues to serve read and write queries while the decommission process streams data to other nodes. When the decommission finishes, the node stops providing CQL service and gossip while leaving the JVM alive.

When decommissioning a DSEFS node, you must unmount DSEFS before removing that node.

Use nodetool netstats to monitor the progress.

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