             Summary: Periodical task checker to detect ping timeout of tasks
                 Key: TAJO-1217
                 URL: https://issues.apache.org/jira/browse/TAJO-1217
             Project: Tajo
          Issue Type: Improvement
            Reporter: Hyunsik Choi


Earlier detection of task failure would improve ultimately query response time in long-running queries. The objective of this issue is to implement the periodical task checker to detect task failure due to ping timeout.

When the checker detects the ping timeout, it should trigger some event and send the event to the corresponding task.
