> h2. Notes
> Right now new node requesting to join cluster may receive reject because of failed security
checks.
> But it is possible that any *GridComponent* may have wrong configuration or internal
state that could lead to cluster instability.
> It is better to identify these situations as early as possible and fail joining process
prohibiting poison nodes to join.
> h2. Acceptance Criteria
> # API for consistency checks is proposed and approved by community.
> # BinaryMetadata cache validation is performed by coordinator. In case of any conflicts
new node joining request is rejected.
> # [Optionally] Security checks are migrated to common mechanism.
