> The {{QuotaRefresherChore}} by default runs every 5 minutes on every RegionServer. This reads the {{hbase:quota}} table, which has a single region hosted on one RegionServer. This means that the larger an HBase cluster grows, the more traffic is directed at the one RegionServer that has the unfortunate role of hosting {{hbase:quota}}.
> In this ticket I will get RegionServers to reload from {{hbase:quota}} when it's modified, and rarely otherwise, to reduce load on the server hosting this table.
