The arbitrator_validity_detail table shows the view that each data node in the cluster has of the arbitrator. All nodes should show the same arbitrator and arb_ticket values as well as the same arb_state value. Possible arb_state values are ...
https://dev.mysql.com/doc/refman/8.0/en/mysql-cluster-ndbinfo-arbitrator-validity-summary.html
The arbitrator_validity_summary table provides a composite view of the arbitrator with regard to the cluster's data nodes. If it has more than 1 row for longer than a few moments, then either not all nodes are connected to the arbitrator, or all ...
