Subject [jira] [Commented] (HBASE-16961) FileSystem Quotas

Josh Elser commented on HBASE-16961:
------------------------------------

bq. Let us know if you need a branch in Apache or not.

Either way, really. I'm not sure if there's a more "common" way to approach this one. If there's
a way for me to be a "branch committer", a branch at Apache would be convenient. Otherwise,
I think it would just be less work for me (and you all) to use my persona branch and we can
just deal with the merge into Apache after all of the work is done.

> 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.
