@InterfaceAudience.Private

public class MasterQuotaManager
extends Object
implements RegionStateListener

Master Quota Manager. It is responsible for initialize the quota table on the first-run and provide the admin operations to interact with the quota table. TODO: FUTURE: The master will be responsible to notify each RS of quota changes and it will do the "quota aggregation" when the QuotaScope is CLUSTER.
