--------------------------------
Summary: PythonScriptEngine copies controller and tajo util
whenever it is initialized
Key: TAJO-1802
URL: https://issues.apache.org/jira/browse/TAJO-1802
Project: Tajo
Issue Type: Bug
Components: Function/UDF
Reporter: Jihoon Son
Assignee: Jihoon Son
Fix For: 0.11.0
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.
