This turned out to be a CCM bug, where decommission would fail silently:

I am unable to reproduce this locally, win8, on 2.2.0-rc1, 2.2-HEAD, or trunk 
using 2.6.0c1:

{noformat}

Only outstanding possibility is that we somehow send the wrong message on 
server12 where we send the correct on win8 but I'm *very* skeptical of that 
both due to a) the message generation logic here having nothing to do with the 
underlying OS to my knowledge and b) server12 and win8 sharing a large portion 
of their libs and kernel logic.

[~kishkaru]: is there a possibility there's something else off in your testing 
environment?

I did have to make some modifications to the test as it's hard-coded expecting 
the tokens to be assigned to node 2 and mine were going to node 3, but after 
inverting the node2/node3 checks the test passes. Will try it on the Server2012 
perf machine as well to confirm. This is with ccm master and 
cassandra-2.2.0-rc1.

If it passes on the server as well I'm going to close this as cannot reproduce 
as it looks like something's up with the testing environment.

So to clarify, it fails through ccmlib, works through ccm on command-line, and

After changing the default connect port (7199) to the Windows listen port 
(7100), I was able to use nodetool from the CLI directly to decommission the 
first node, 127.0.0.1. While CCM's node status was not updated, I was able to 
verify via nodetool status that the node no longer exists in the ring. However, 
the Java process still exists for the decommissioned node.  

Furthermore, I'm still able to query the decommissioned node through both CCM:

 Key: CASSANDRA-9584
 URL: https://issues.apache.org/jira/browse/CASSANDRA-9584
 Project: Cassandra
  Issue Type: Bug
 Environment: C* 2.2.0-rc1 | python-driver 2.6.0-rc1 | Windows Server 
 2012 R2 64-bit
Reporter: Kishan Karunaratne

 Decommissioning a node on Windows sends the wrong schema change event:
 {noformat}
 cassandra.connection: DEBUG: Message pushed from server: 
 EventMessage(event_type=u'STATUS_CHANGE', trace_id=None, event
 _args={'change_type': u'DOWN', 'address': ('127.0.0.2', 9042)}, stream_id=-1)
 {noformat}
 On Linux I get the correct event:
 {noformat}
 cassandra.connection: DEBUG: Message pushed from server: 
 EventMessage(event_type=u'TOPOLOGY_CHANGE', trace_id=None, 
 event_args={'change_type': u'REMOVED_NODE', 'address': ('127.0.0.2', 9042)}, 
 stream_id=-1)
 {noformat}
 We are using ccmlib node.py.decommission() which calls nodetool decommission:
 {noformat}
 def decommission(self):
 self.nodetool(decommission)
 self.status = Status.DECOMMISIONNED
 self._update_config()
 {noformat}
 Interestingly, it does seem to work (correctly?) on CCM CLI:
 {noformat}
 PS C:\Users\Administrator ccm status
 Cluster: '2.2'

 node1: UP
 node3: UP
 node2: UP
 PS C:\Users\Administrator ccm node1 ring

When I stopped and started the cluster via CCM, the decommissioned node 
returned to the ring. Is this expected behavior?
