[jira] [Created] (TAJO-1215) ResourceTracker should notify node failure to QueryMaster

Hyunsik Choi created TAJO-1215:
----------------------------------

             Summary: ResourceTracker should notify node failure to QueryMaster
                 Key: TAJO-1215
                 URL: https://issues.apache.org/jira/browse/TAJO-1215
             Project: Tajo
          Issue Type: Improvement
            Reporter: Hyunsik Choi


*Problem*
ResourceTracker (RT) is a component which firstly can detects node failure. BTW, currently RT does not notify the detected node failure to QueryMaster. So, QM is delayed to handle node failure. As a result, mid-query fault tolerance can be failed or delayed.

*Solution*
RT immediately notifies some node failure to a corresponding QM.
