> Key: FLINK-17609
> URL: https://issues.apache.org/jira/browse/FLINK-17609
> Project: Flink
> Issue Type: Bug
> Components: API / Python, Client / Job Submission
> Affects Versions: 1.11.0
> Reporter: shuiqiangchen
> Priority: Major
> Labels: pull-request-available
> Fix For: 1.11.0

>
> Currently, the PythonDriver will always construct the python execution
> command with "-m" option, which means uses code files will run as a module,
> E.g, "python -m <module_name>". However, when user specifies the "-py" option
> followed by the entry script file path, we should directly execute the user
> specified script, such as "python <entry_script_file_path>".
> The difference between "python <entry_script_file_path>" and "python -m
> <module_name>" is as follow:
> "python <entry_script_file_path>" will add the parent directory of the
> entry script to the PYTHONPATH so that all modules under the directly can be
> found when executing the script.
> "python -m <module_name>" will only add the current execution directory
> to the PYTHONPATH, which may cause "ModuleNotFoundError" when the entry
> module references other modules under the same directory.
