@guan46 If you accidentially close a PR, it can be reopened. It's better to continue on the original PR. I'll close this one and reopen the original one.

Oh, I see why #23904 was closed. It used your master branch. When creating pull requests, it's necessary to aways create a branch so that you don't run into the issue. I'll reopen this one and let's continue on this PR.

I updated https://pulsar.apache.org/contribute/personal-ci/ instructions with relevant information.

What you should do is to ensure that tests pass with your changes. If not, it's either a flaky test or your changes break the tests.
For example this test breaks: https://github.com/guan46/pulsar/actions/runs/13072194671/job/36541465274?pr=3#step:11:2705 .

If you think that a test failure could be a flaky test, you can "re-run failed jobs" in the GitHub Actions UI.

For actual test failures caused by your changes, you should run them in IDE and debug the reasons why they fail with your changes. It would be pointless if a contributor makes PRs without handling this step on their own.
