Roman Puchkovskiy updated IGNITE-22804:
---------------------------------------
Labels: iep-128 ignite-3 (was: ignite-3)
> Refuse network handshake if nodes have different cluster IDs
> ------------------------------------------------------------
>
> Key: IGNITE-22804
> URL: https://issues.apache.org/jira/browse/IGNITE-22804
> Project: Ignite
> Issue Type: Improvement
> Reporter: Roman Puchkovskiy
> Assignee: Roman Puchkovskiy
> Priority: Major
> Labels: iep-128, ignite-3
> Fix For: 3.0.0-beta2
>
> Time Spent: 0.5h
> Remaining Estimate: 0h
>
> When a node is joined to a cluster for the first time, the node gets the
> cluster ID from the CMG. The node then saves the cluster ID locally.
> We should validate that cluster IDs of the nodes are the same when the nodes
> try to establish a network connection: that is, during a handshake, if both
> cluster IDs are not empty and are different, we should fail the handshake.
> If one of the nodes does not have a cluster ID yet, the validation is skipped.
> Having this validation will allow to avoid mixing of the 'new part' of the
> cluster (where CMG was recreated) with the 'old part' of the cluster (that
> was not available during CMG recreation).
