Hi, If it already uses 100 % CPU I have a hard time seeing it being able to do a decomission while serving requests. If you have a lot of free space I would first try nodetool disableautocompaction. If you don't see any progress in nodetool netstats you can also disablebinary, disablethrift and disablehandoff to stop serving client requests.
