[GitHub] [pulsar] lhotari opened a new issue, #15850: Flaky-test: MultiTopicsConsumerImplTest.testParallelSubscribeAsync
lhotari opened a new issue, #15850:
URL: https://github.com/apache/pulsar/issues/15850
<!---
Instructions for reporting a flaky test using this issue template:
1. Replace test_class in title and body with the short test class name WITHOUT the package name.
2. Replace test_method in title and body with the test method that failed. Multiple methods are flaky, remove the content that refers to the test method.
3. Replace "url here" with a url to an example failure. In the Github Actions workflow run logs, you can right click on the line number to copy a link to the line. Example of such url is https://github.com/apache/pulsar/pull/8892/checks?check_run_id=1531075794#step:9:377 . The logs are available for a limited amount of time (usually for a few weeks).
4. Replace "relevant parts of the exception stacktrace here" with the a few lines of the stack trace that shows at least the exception message and the line of test code where the stacktrace occurred.
5. Replace "full exception stacktrace here" with the full exception stacktrace from logs. This section will be hidden by default.
6. Remove all unused fields / content to unclutter the reported issue. Remove this comment too.

MultiTopicsConsumerImplTest.testParallelSubscribeAsync is flaky. It fails sporadically.
[example failure](https://github.com/lhotari/pulsar/runs/6660340044?check_suite_focus=true#step:10:8126)
```
Error: Tests run: 9, Failures: 2, Errors: 0, Skipped: 3, Time elapsed: 18.637 s <<< FAILURE! - in org.apache.pulsar.client.impl.MultiTopicsConsumerImplTest
Error: testParallelSubscribeAsync(org.apache.pulsar.client.impl.MultiTopicsConsumerImplTest) Time elapsed: 5.006 s <<< FAILURE!
org.testng.internal.thread.ThreadTimeoutException: Method org.apache.pulsar.client.impl.MultiTopicsConsumerImplTest.testParallelSubscribeAsync() didn't finish within the time-out 5000
```
More logs in [org.apache.pulsar.client.impl.MultiTopicsConsumerImplTest-output.txt](https://gist.githubusercontent.com/lhotari/17f690fd839ce3717a832fb6f972e374/raw/15e4c2b8bce348fe41437e5d55693a5cafc67530/org.apache.pulsar.client.impl.MultiTopicsConsumerImplTest-output.txt) from surefire reports.
Several problems:
```
Error connecting to broker: java.lang.NullPointerException: Cannot invoke "org.apache.pulsar.client.api.Schema.getSchemaInfo()" because "this.schema" is null {}
```
An odd NoClassDefFoundError in logs (similar to observation https://github.com/apache/pulsar/pull/15762#issuecomment-1136786473):
