I discovered problem with this advice.

If i do nodetool drain before killing node nodetool returns just after 
flush and stuff disabling is finished on cassandra node. But flush can 
trigger possible compaction and if you kill node after drain it will 
interrupt compaction in progress resulting in wasted disk space. I am 
not sure if tmp files are cleaned on cassandra start.
