[jira] [Created] (TAJO-654) Separate TajoWorker into yarn worker and standby worker

Hyunsik Choi created TAJO-654:
---------------------------------

             Summary: Separate TajoWorker into yarn worker and standby worker
                 Key: TAJO-654
                 URL: https://issues.apache.org/jira/browse/TAJO-654
             Project: Tajo
          Issue Type: Improvement
          Components: worker
            Reporter: Hyunsik Choi
            Assignee: Hyunsik Choi
             Fix For: 1.0-incubating


TajoWorker can play two roles for yarn and standby modes, and the role is set by some parameter. Also, in standby mode, TajoWorker has additional two modes, which are query master mode and task runner mode. TajoWorker has too many roles. The objective of this issue is to simplify TajoWorker and separate multiple roles into driver classes.
