DISABLED test_create_store_single_server (__main__.DistributedUtilTest)

[janeyx99]

Flaky on CI, for example in this https://github.com/pytorch/pytorch/runs/3816958493?check_suite_focus=true.

This was on the 10.2 linux build.

A better log view can be found by expanding on the linux 10.2 distributed tests here: https://hud.pytorch.org/commit/b8e19992533a2257f457926e6535f54054fc2003

Hello there! From the DISABLED prefix in this issue title, it looks like you are attempting to disable a test in PyTorch CI. The information I have parsed is below:

• Test name: test_create_store_single_server (__main__.DistributedUtilTest)
• Platforms for which to skip the test: none parsed, defaulting to ALL platforms

Within ~15 minutes, test_create_store_single_server (main.DistributedUtilTest) will be disabled in PyTorch CI for all platforms. Please verify that your test name looks correct, e.g., test_cuda_assert_async (__main__.TestCuda).

To modify the platforms list, please include a line in the issue body, like below. The default action will disable the test for all platforms if no platforms list is specified.

Platforms: case-insensitive, list, of, platforms

We currently support the following platforms: asan, linux, mac, macos, rocm, win, windows.

Looks like the fix for this test will be similar to the one in #66953, I believe that test_create_store_single_server just needs to pass port = 0 as an argument into create_c10d_store. Additional investigation needs to be done into why create_c10d_store is not retrying the port allocation after failing.

Hm it looks like this is still not disabled on CI as I recently just found https://ci.pytorch.org/jenkins/job/pytorch-builds/job/pytorch-linux-bionic-rocm4.3.1-py3.6-test-distributed/3292//console from 11/2/21. It's probably due to the elastic tests not overloading our TestCase class--addressing with #67700
