Brandon Williams commented on CASSANDRA-7069:
---------------------------------------------
Without looking at that patch, will it gracefully handle starting a bunch of
nodes up in bootstrap mode at once?
> Prevent operator mistakes due to simultaneous bootstrap

> Key: CASSANDRA-7069
> URL: https://issues.apache.org/jira/browse/CASSANDRA-7069
> Project: Cassandra
> Issue Type: New Feature
> Components: Core
> Reporter: Brandon Williams
> Assignee: Brandon Williams
> Priority: Minor
> Fix For: 3.0
>
>
> 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.
