We would like to take a node out of the ring and upgradesstables while it is 
not doing any writes nor reads with the ring.  Is this possible?

I am thinking from the documentation

 1.  nodetool drain
 2.  ANYTHING to stop reads here????
 3.  Modify cassandra.yaml with compaction_throughput_mb_per_sec = 0 and 
multithreaded_compaction = true temporarily
 4.  Restart cassandra and run nodetool upgradesstables keyspace CF
 5.  Modify cassandra.yaml to revert changes
 6.  Restart cassandra to join the cluster again.

Is this how it should be done?

Thanks,
Dean
