---------------------------------------
Summary: 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
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.
