             Summary: Removing SpaceQuota from a namespace does not remove it completely
                 Key: HBASE-20820
                 URL: https://issues.apache.org/jira/browse/HBASE-20820
             Project: HBase
          Issue Type: Bug
            Reporter: Nihal Jain
            Assignee: Nihal Jain


As demonstarted in [HBASE-20662.master.002.patch|https://issues.apache.org/jira/secure/attachment/12927187/HBASE-20662.master.002.patch] setting quota on a namespace and removing it does not remove the quota setting from the tables in the namespace (which were added systematically due to namespace quota settings).

*Relevant code:*
{code:java}
public void setQuotaAndThenRemove(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"));
  // Set quota and do puts until we violate space policy
  final TableName tn = writeUntilNSSpaceViolationAndVerifyViolation(namespace, policy, put);
  // Now, remove the quota
  removeQuotaFromNamespace(namespace);
  // Put some rows now: should not violate as quota settings removed
  verifyNoViolation(policy, tn, put);
}
{code}
