> Reload quotas from hbase:quota table when changes are made

> Key: HBASE-29387
> URL: https://issues.apache.org/jira/browse/HBASE-29387
> Project: HBase
> Issue Type: Improvement
> Reporter: Charles Connell
> Assignee: Charles Connell
> Priority: Minor
> Labels: pull-request-available
> Fix For: 2.7.0, 3.0.0-beta-2, 2.6.3

>
> 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.
