> Key: HBASE-22142
> URL: https://issues.apache.org/jira/browse/HBASE-22142
> Project: HBase
> Issue Type: Bug
> Affects Versions: 2.1.1
> Reporter: Shardul Singh
> Priority: Minor
> Attachments: HBASE-22142.branch-2.1.v001.patch
>
>
> steps to follow:
> 1.create a quota at namespace level
> 2.create 2 tables t1 and t2 inside namespace and write data.
> 3.write 5 mb of data each in both t1 and t2.
> 4. drop t1.
> 5. data usage for t2 will be shown 10 mb for 10 minutes.
> If table is dropped inside namespace, data size usage is still shown for 10
> minutes because of the configuration
> "hbase.master.quotas.region.report.retention.millis". This conf maintains the
> region report in cache(regionSizes) and old entry is used for 10 minutes. We
> can remove the entry from cache during the drop command as part of MasterCP
> hook only, so that correct usage is show instantaneously after the drop
> command.
