nodetool decommission

Causes a live node to decommission itself, streaming its data to the next node on the ring to replicate appropriately.

When decommissioning a HCDFS node, you must zref:analytics/commands-HCDFS.adoc#removingHCDFSNode[unmount HCDFS] before removing that node.

nodetool decommission does not shut down the node. Shut down the node after decommission is complete.
