Sorry for joining the party so late, but I think the solution is
incomplete. Flink displays many metrics for the different components of the
system. For example, the `TaskManagersHandler` displays the memory of the
respective `TaskManagers`. If we say, we don't want to display metric
information if it's not complete, then this should be fixed as well.---
