             Summary: Consistency checks and error tracking during node joining process
                 Key: IGNITE-4679
                 URL: https://issues.apache.org/jira/browse/IGNITE-4679
             Project: Ignite
          Issue Type: Improvement
          Components: general
            Reporter: Sergey Chugunov


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.
