Key: HBASE-20821
URL: https://issues.apache.org/jira/browse/HBASE-20821
Project: HBase
Issue Type: Bug

As demonstarted in

re-creating a dropped namespace and contained table inherits previously set
space quota settings.
*Steps*
* Create a namespace and a table in it
* Set space quota on namespace
* Drop table and then namespace
* Re create same namespace and same table
*
{code:java}
private void setQuotaAndThenDropNamespace(final String namespace,
SpaceViolationPolicy policy)
throws Exception {
Put put = new Put(Bytes.toBytes("to_reject"));
put.addColumn(Bytes.toBytes(SpaceQuotaHelperForTests.F1), Bytes.toBytes("to"),
Bytes.toBytes("reject"));
createNamespaceIfNotExist(TEST_UTIL.getAdmin(), namespace);
// Do puts until we violate space policy
final TableName tn = writeUntilNSSpaceViolationAndVerifyViolation(namespace,
policy, put);
// Now, drop the table
TEST_UTIL.deleteTable(tn);
LOG.debug("Successfully deleted table ", tn);
// Now, drop the namespace
TEST_UTIL.getAdmin().deleteNamespace(namespace);
LOG.debug("Successfully deleted the namespace ", namespace);
// Now re-create the namespace
createNamespaceIfNotExist(TEST_UTIL.getAdmin(), namespace);
LOG.debug("Successfully re-created the namespace ", namespace);
TEST_UTIL.createTable(tn, Bytes.toBytes(SpaceQuotaHelperForTests.F1));
LOG.debug("Successfully re-created table ", tn);
// Put some rows now: should not violate as namespace/quota was dropped
verifyNoViolation(policy, tn, put);
}
{code}
*Expected*: SpaceQuota settings should not exist on the newly re-created table
*Actual:* SpaceQuota settings (systematically created due to previously added
namespace space quota) exist on table
