> The master schedules a SCP for the region server hosting meta. However, due to a misconfiguration, the cluster cannot make progress. After fixing the configuration issue and restarting, the cluster still cannot make progress. After the configured period (15 minuets), the master enters a "holding pattern" where it retains Active master status, but isn't taking any action.
> This "brown-out" state is toxic. It should either keep trying to make progress, or it should abort. Staying up and not doing anything is the wrong thing to do.
