Josh Elser commented on HBASE-17002:
------------------------------------
One issue that I ran into is that there is no good way to do expose a
{{CompositeData}} object via the hbase metrics and hadoop metrics2 API. The
CompositeData class is what is used to make a little "closure", like...
{noformat}
"t1" : {
usage=1234,
limit = 5678
},
...
{noformat}
So, that's why there's the little json blob in tag.tableSpaceQuotaOverview and
tag.namespaceSpaceQuotaOverview
> [Master] Report quotas and active violations on Master UI and JMX metrics

> We should be able to view the Master UI and determine what quotas exist and
> the quotas that are in violation to easily confirm/deny the state of
> tables/namespaces.
> The JMX metrics from the Master should also include the list of
> tables/namespaces which have quotas whose violation policies are presently
> being enforced.
