If after, you have violated consistency in a manner that, in my understanding, one cannot recover from. If before, you're pretty fine. However this is a longstanding issue that I personally consider a bug : Your decommissioned node doesn't forget its state. In my opinion, you told it to leave the cluster, it should forget everything it knew as a member of that cluster. If you file this behavior as a JIRA bug, please let the list know. =Rob
