      Description

      In the current implementation, python script files are copied and deleted whenever a task is launched and stopped. This incurs two problems.

      • Frequent copy of script files degrades the overall performance.
      • Among python scripts, tajo_util.py is shared by multiple tasks of a worker. This incurs I/O problem during unit tests because the shared file is also removed when a task is stopped.
