Jonathan Ellis commented on CASSANDRA-435:
------------------------------------------
> When node is decommisioned, should it delete its saved token? If the same
> node is brought back online without manual data deletion, it will enter the
> ring without proper bootstrap.

is harmless and may be useful to someone.
> unbootstrap
