[jira] [Created] (TAJO-1940) Implement HBaseTablespace::getTableVolume() method

Jihoon Son created TAJO-1940:
--------------------------------

             Summary: Implement HBaseTablespace::getTableVolume() method
                 Key: TAJO-1940
                 URL: https://issues.apache.org/jira/browse/TAJO-1940
             Project: Tajo
          Issue Type: Task
          Components: HBase Storage
            Reporter: Jihoon Son
             Fix For: 0.11.1


Table volume has an important role in query planning. Tajo's query optimizer makes many decisions based on table volume, because it is currently the only available statistics. 

However, HBaseTablespace doesn't support getTableVolume() method, so our plan is not good when the query involves any HBase tables.
