What changes were proposed in this pull request?

This PR proposes to skip the tests that fail with 3.5 client and 4.0 server in Spark Connect (by adding SPARK_SKIP_CONNECT_COMPAT_TESTS). This is a base work for #46298. This partially backports #45870

This PR also adds SPARK_CONNECT_TESTING_REMOTE environment variable so developers can run PySpark unittests against a Spark Connect server.

Why are the changes needed?

In order to set up the CI that tests 3.5 client and 4.0 server in Spark Connect.

Does this PR introduce any user-facing change?

No, test-only.

How was this patch tested?

Tested it in my fork, see #46298

Was this patch authored or co-authored using generative AI tooling?

No.

I am going to forward port a bit of changes into master to reduce the diff later.

Oh, I thought Spark Connect is supposed to handle this, @HyukjinKwon .

Do you know what breaks the compatibility?

HyukjinKwon commented May 3, 2024

Spark Connect is actually for testing pure python library. Spark 3.5 doesn't have it ... from 4.0 <> 4.1, we could leverage pure python library build to test them. I will try to reuse that build instead of duplicating some like this

I am triaging the breaking changes in the umbrella JIRA at https://issues.apache.org/jira/browse/SPARK-48082. They are mostly because of new features so it seems not so bad.

Oh, could you re-trigger the failed pyspark tests to make it sure? It looks irrelevant though.
