----------------------------------
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.
