Subject Re: is "Not a time-based UUID" serious?
Date Wed, 12 Sep 2012 23:43:53 GMT
To answer my own question: yes, the error is fatal.  This also means that
upgrades to 1.1.x from 1.0.x MUST use 1.0.11 or greater it seems to be
successful.

My test upgrade from 1.0.9 to 1.1.5 left the cluster in a state that wasn't
able to come to a schema agreement and blocked schema changes.
