-------------------------------------

             Summary: TableNotFoundException: hbase:quota  is thrown when region server is restarted.
                 Key: HBASE-22944
                 URL: https://issues.apache.org/jira/browse/HBASE-22944
             Project: HBase
          Issue Type: Bug
          Components: Quotas
            Reporter: Shardul Singh
            Assignee: Shardul Singh


SpaceQuotaRefresherChore does not checks whether hbase:quota table is present,before starting its operation which sometimes may result to TableNotFoundExceptions like below.

This is becuase master has not created the hbase:quota table and SpaceQuotaRefresherChore is running.

```
