Is it ok to add more than one node to a exist cluster
Hi,
I have read a warning of not Simultaneously bootstrapping more than one new node from the same rack in version 2.1 link
My cassandra cluster version is 3.0.10.
So I wonder to know Is it ok to add more than one node to a exist cluster in 3.0.10.
Thanks!
Dayu

To clarify, this is after the node reaches NORMAL state. don't bootstrap
other nodes while one is in JOINING unless you really know what you are
doing and aren't using vnodes.

another question, Can I bootstrap a new node when some node is in Joining state ? Or I should wait until Joining node becoming Normal ?

Theres always an 2 minute rule ..after adding one node wait for 2 minutes
before addding second node.

Thanks for your reply, kurt.
another question, Can I bootstrap a new node when some node is in Joining state ? Or I should wait until Joining node becoming Normal ?

Don't bootstrap nodes simultaneously unless you really know what you're
doing, and you're using single tokens. It's not straightforward and will
likely lead to data loss/inconsistencies. This applies for all current
versions.
