Andrew Purtell commented on HBASE-16961:
----------------------------------------
[~elserj] A couple of high level questions.
1. About the optional MasterObserver for automatically deleting quotas when the
table is deleted. Why do we not want this in general? Make it a part of core
master, optionally disabled?
2. Under what circumstances is NO_WRITES_COMPACTIONS advisable instead of
NO_WRITES?
3. How would quotas and system recovery actions interact? Are quota checks
bypassed for actions taken by a superuser?

> URL: https://issues.apache.org/jira/browse/HBASE-16961
> Project: HBase
> Issue Type: New Feature
> Reporter: Josh Elser
> Assignee: Josh Elser
> Attachments: hbase-quota-test.sh
>
>
> Umbrella issue for tracking the filesystem utilization of HBase data,
> defining quotas on that utilization, and enforcement when utilization exceeds
> the limits of the quota.
> At a high level: we can define quotas on tables and namespaces. Region size
> is computed by RegionServers and sent to the Master. The Master inspects the
> sizes of Regions, rolling up to table and namespace sizes. Defined quotas in
> the quota table are evaluated given the computed sizes, and, for those
> tables/namespaces violating the quota, RegionServers are informed to take
> some action to limit any further filesystem growth by that table/namespace.
