LGTM, thanks, just bumped into this myself when externalizing the Cassandra Python connector.

Tested on Mac M1 OS 14.2.1, also worked for me!

@dianfu can you pls. check on this if you have some time? Thanks!

LGTM.

It would be good to change in Flink main repo too.

Thanks for the feedback @gaborgsomogyi, I see that main repo has newer miniconda versions in the script:
Miniconda3-py310_23.5.2-0-{OS} in main vs Miniconda3-4.7.12.1-{OS} here.
https://github.com/apache/flink/blame/master/flink-python/dev/lint-python.sh#L200-L203

I will verify that version in main repo works and update this PR to align versions.

I've just taken a small look at the release date of the mentioned version and seems like it's released on 2019-10-25. Is it possible to use a more recent version to catch up?

@pvary do you remember why we added the old conda version here?

IIRC the issue was to run the python tests on Mac with the new Python versions

[gaborgsomogyi]

@pvary Thanks! Now I remember that the newest conda version would work when the connector would bump Flink version. Merging...

Thanks for the fix!
