Nick Bailey updated CASSANDRA-1216:
-----------------------------------

    Attachment: 0001-Modify-removeToken-command-to-make-it-similar-to-dec.patch
                0002-Fixes-to-old-tests.patch

* 0001 - changes to make removeToken behave similarly to decomission
* 0002 - fixes to existing tests since the state for STATE_LEFT changed

I am still working on some good unit tests for these changes but these are the changes so far.

The new process for removeToken is basically the one outlined above. One change is that instead of a STATE_REMOVED state it seemed like tokens that are removed should just go into STATE_LEFT similar to nodes that are decommissioned.

One thing I'm not sure of is the timeout values for waiting for replications to stream and for waiting for replication notifications. Currently they are just set arbitrarily in that patch. Need to determine good values for these.

> this means that if something goes wrong during the re-replication (e.g. a source node is restarted) there is (a) no indication that anything has gone wrong and (b) no way to restart the process (other than the Big Hammer of running repair)
