Brandon Williams updated CASSANDRA-7939:
----------------------------------------
    Attachment: 7939.txt

A simple enough fix for 2.0.  Unfortunately for 2.1, bypassing this problem causes a new one for CASSANDRA-7069, since we can begin bootstrapping before we've seen the entire ring.  I think we'll have to check STATUS for each node in cFEC and bail if we see JOINING or LEAVING, since tMD won't be populated from the shadow round.

> If you fail a bootstrap, then immediately retry it, cFEC erroneously tells you to replace it:

> ERROR 00:04:50 Exception encountered during startup
> java.lang.RuntimeException: A node with address bw-3/10.208.8.63 already exists, cancelling join. Use cassandra.replace_address if you want to replace this node.
