Shardul Singh created HBASE-22142:
-------------------------------------
Summary: Space quota: If table is dropped inside namespace, data
size usage is still considered for the drop table.
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
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 during the drop command only, so that correct usage is
show instantaneously after the drop command.
