Brandon Williams updated CASSANDRA-7069:
----------------------------------------
Description:
Cassandra has always had the '2 minute rule' between beginning topology changes
to ensure the range announcement is known to all nodes before the next one
begins. Trying to bootstrap a bunch of nodes simultaneously is a common
mistake and seems to be on the rise as of late.
We can prevent users from shooting themselves in the foot this way by looking
for other joining nodes in the shadow round, then comparing their generation
against our own and if there isn't a large enough difference, bail out or sleep
until it is large enough.
