Re: auto_bootstrap for seed node
Setting auto_bootstrap on seed nodes is unnecessary and irrelevant. If the node is a seed it will ignore auto_bootstrap and it *will not* bootstrap.

Re: auto_bootstrap for seed node
"it seems that we still need to keep bootstrap false?" Could you shed some light on what would happen if the auto_bootstrap is removed (or set to true as the default value) in the seed nodes of the newly added DC? What do you have in the seeds param of the new DC nodes (cassandra.yaml)? Do you reference the old DC seed nodes there as well?
