It is used to force remove a node from gossip membership if something goes wrong. Note: run the force_remove_endpoint api at the same time on _all_ the nodes in the cluster in order to prevent the removed nodes come back. Becasue nodes without running the force_remove_endpoint api cmd can gossip around the removed node information to other nodes in 2 * ring_delay (2 * 30 seconds by default) time. For instance, in a 3 nodes cluster, node 3 is decommissioned, to remove node 3 from gossip membership prior the auto removal (3 days by default), run the api cmd on both node 1 and node 2 at the same time. $ curl -X POST --header "Accept: application/json" "http://127.0.0.1:10000/gossiper/force_remove_endpoint/127.0.0.3" $ curl -X POST --header "Accept: application/json" "http://127.0.0.2:10000/gossiper/force_remove_endpoint/127.0.0.3" Then run 'nodetool gossipinfo' on all the nodes to check the removed nodes are not present.
