It seems like tests were added by:

commit 67148254146948041a77d8a2989f41b88cdb2f99
Author: Jason R. Coombs <jaraco@jaraco.com>
Date:   Thu Mar 4 13:43:00 2021 -0500

    bpo-42129: Add support for resources in namespaces (GH-24670)
    
    * Unify behavior in ResourceReaderDefaultsTests and align with the behavior found in importlib_resources.
    * Equip NamespaceLoader with a NamespaceReader.
    * Apply changes from importlib_resources 5.0.4
msg389175 - (view) Author: Jason R. Coombs (jaraco) * (Python committer) Date: 2021-03-20 19:44
Interestingly, the pull request never alerted to any buildbot failures.

Any idea how I can reproduce the issue locally? Is there a docker image that would likely replicate the environment in which the tests are failing?
msg389182 - (view) Author: Jason R. Coombs (jaraco) * (Python committer) Date: 2021-03-20 21:47
Oh, "installed python". So maybe Python requires one register files in more than one place to add them to the installation.

I've submitted a PR and triggered build by buildbots, but I don't see that the indicated builder is building the PR. Shall I just submit and see what happens? Any other ideas how to verify the installed builder buildbots?

You can find your submitted change here by looking here:
https://buildbot.python.org/all/#/changes

For some reason, though, it seems that no build was triggered:
https://buildbot.python.org/all/#/changes/3344

In any case, the fix is a no-brainer.

New changeset 9a50ef43e42ee32450a81ce13ed5a0729d3b84e8 by Jason R. Coombs in branch 'master':
bpo-43569: Add test/test_importlib/namespacedata01 to TESTSUBDIRS (GH-24952)
https://github.com/python/cpython/commit/9a50ef43e42ee32450a81ce13ed5a0729d3b84e8
msg389255 - (view) Author: Jason R. Coombs (jaraco) * (Python committer) Date: 2021-03-21 18:24
Unfortunately, it seems the patch didn't have the intended effect. The [build is still failing](https://buildbot.python.org/all/#/builders/14/builds/810). So I'm left without a way to test without committing code to the main branch.
msg389256 - (view) Author: Antoine Pitrou (pitrou) * (Python committer) Date: 2021-03-21 18:40
I don't think that build includes your change.
Here are the builds that have been triggered (the list seems incomplete for now):
https://buildbot.python.org/all/#/changes/3355
msg389257 - (view) Author: Jason R. Coombs (jaraco) * (Python committer) Date: 2021-03-21 18:43
Okay, I think you may be right. I saw your name on the build and assumed that meant the merge triggered that build. I'll trigger a build now.
msg389258 - (view) Author: Jason R. Coombs (jaraco) * (Python committer) Date: 2021-03-21 18:46
Assuming Antoine is correct (a likely story), I'm closing and will only re-open if a subsequent failure is confirmed to have run and failed after the submission. Sorry for the noise.
msg389287 - (view) Author: STINNER Victor (vstinner) * (Python committer) Date: 2021-03-22 09:01
I confirm that aarch64 Fedora Stable Clang Installed 3.x is back to green, thanks for the fix.
