Will the failure of a MySQL Cluster Manager agent impact the availability of the MySQL Cluster database?

No. To ensure high availability operation, MySQL Cluster Manager is decoupled from the actual database processes, so if a management agent stops or is upgraded, it does not impact the running database in any way. MySQL Cluster Manager continues to operate across surviving nodes when any given agent or the associated host is not available.
