[jira] [Created] (TAJO-266) Extend ExecutionBlock and Task to support multiple outputs

Jihoon Son created TAJO-266:
-------------------------------

             Summary: Extend ExecutionBlock and Task to support multiple outputs
                 Key: TAJO-266
                 URL: https://issues.apache.org/jira/browse/TAJO-266
             Project: Tajo
          Issue Type: Task
          Components: distributed query plan, worker
            Reporter: Jihoon Son
            Assignee: Jihoon Son


In the current Tajo, every task has the only one output.
However, supporting multiple outputs per task very useful for the distributed plan optimization.
