Subject [jira] [Created] (KAFKA-10662) Possible hanging test in 2.6 on JDK 11
Date Thu, 29 Oct 2020 19:01:00 GMT
John Roesler created KAFKA-10662:

             Summary: Possible hanging test in 2.6 on JDK 11
                 Key: KAFKA-10662
                 URL: https://issues.apache.org/jira/browse/KAFKA-10662
             Project: Kafka
          Issue Type: Bug
    Affects Versions: 2.6.1
            Reporter: John Roesler
         Attachments: timeout-1.txt, timeout-2.txt, timeout-4.txt

While adding a Jenkinsfile to the 2.6 branch ([https://github.com/apache/kafka/pull/9471),]

I observed the JDK 11 build specifically to hang, 3/5 times (and pass within a normal timeframe
of 2.5 hours the other two times).

I haven't seen similar behavior on any other branch, so there may be something about the 2.6
codebase or the 2.6 tests themselves that interact poorly with Java 11.


I did some analysis on the failing results, and found that in all three hanging cases, all
the tests that "STARTED" either "PASSED" or were "SKIPPED". So, I was not able to identify
a specific culprit. I've attached the logs for these runs, in case they aid any investigation.
