             Summary: Allow PYTHONPATH of Python Worker to be configurable
                 Key: FLINK-30277
                 URL: https://issues.apache.org/jira/browse/FLINK-30277
             Project: Flink
          Issue Type: Improvement
          Components: API / Python
    Affects Versions: 1.16.0
            Reporter: Prabhu Joseph


Currently, below are the ways Python Worker gets the Python Flink Dependencies.
 # Worker Node's System Python Path (/usr/local/lib64/python3.7/site-packages)
 # Client passes the python Dependencies through -pyfs and --pyarch which is localized into PYTHONPATH of Python Worker.
 # Client passes the requirements through -pyreq which gets installed on Worker Node and added into PYTHONPATH of Python Worker.

This Jira intends to allow PYTHONPATH of Python Worker to be configurable where admin/Service provider can install the required python flink depencies on a custom path (/usr/lib/pyflink/lib/python3.7/site-packages) on all Worker Nodes and then set the path in the client machine configuration flink-conf.yaml. This way it works without any configurations from the Application Users and also without affecting any other components dependent on System Python Path.
