PrabhuJoseph opened a new pull request, #23700:
URL: https://github.com/apache/flink/pull/23700
## What is the purpose of the change
Currently, the PYTHONPATH includes only platlib
(lib64/python3.7/site-packages) in Python 3.7. Some of the Python packages,
like cloudpickle, are installed in purelib (lib/python3.7/site-packages)
instead of platlib, and so the pyflink jobs are failing with the below error.
This change is to include both purelib and platlib as part of PYTHONPATH.
`
No module named 'cloudpickle
`
```
[hadoop@ip-1-2-3-4 tmp]$ python --version
Python 3.7.16
[hadoop@ip-172-31-44-103 tmp]$ python -m sysconfig | grep site
platlib = "/usr/lib64/python3.7/site-packages"
purelib = "/usr/lib/python3.7/site-packages"
