Subject [jira] [Created] (HBASE-16961) FileSystem Quotas
Date Fri, 28 Oct 2016 16:26:58 GMT
Josh Elser created HBASE-16961:

             Summary: FileSystem Quotas
                 Key: HBASE-16961
                 URL: https://issues.apache.org/jira/browse/HBASE-16961
             Project: HBase
          Issue Type: New Feature
            Reporter: Josh Elser
            Assignee: Josh Elser

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.
