@manuzhang I think we can just skip the "fuzz" suite and keep the other Spark 4 tests active for macOS

This failed test looks like a flaky one

Thanks @andygrove
btw WDYT to optimize test process in future and start fuzz testing before the release only or if some specific files were changed?

That sounds great. Do you have an idea about how we can achieve this?

We can take Datafusion examples https://github.com/apache/datafusion/blob/33ac70dd6d634da040cc34abd414425b176a2b99/.github/workflows/extended.yml#L43

so extended tests are triggered if PR is for release branch branch-* or if any PR modifies core in

      - 'datafusion/physical*/**/*.rs'
      - 'datafusion/expr*/**/*.rs'
      - 'datafusion/optimizer/**/*.rs'

With latest PRs Comet modularity changes can open doors now for this test conditional trigger?
