Causes a live node to decommission itself, streaming its data to the next node on the ring to replicate appropriately.
When decommissioning a DSEFS node, you must unmount DSEFS before removing that node.

Tip: Use nodetool netstats to monitor
the progress.
Note:
nodetool decommission does not shut down the node. Shut down the
node after decommission is complete.Synopsis
