Brandon Williams commented on CASSANDRA-3118:
---------------------------------------------
bq. Why does the decommission node automatically join the cluster when it
restarts?
Because doing so is operator error. We don't delete data unless the operator
says to, so that is normal, it can rejoin if needed.
> nodetool can not decommission a node
