Description

Hello,

I tried system tests as per: (https://github.com/apache/kafka/tree/trunk/tests#readme)

=========================================================
PROBLEM
~~~~~~
git clone https://github.com/apache/kafka.git && cd kafka
bash tests/docker/run_tests.sh

Tests stall after a while (log attached): -
[INFO:2021-09-22 06:08:41,637]: Triggering test 37 of 882...
[INFO:2021-09-22 06:08:41,650]: RunnerClient: Loading test {'directory': '/opt/kafka-dev/tests/kafkatest/tests/core', 'file_name': 'throttling_test.py', 'cls_name': 'ThrottlingTest', 'method_name': 'test_throttled_reassignment'}

File "/opt/kafka-dev/tests/kafkatest/services/monitor/http.py", line 191, in stop
if self._accept_thread.isAlive(): AttributeError: 'Thread' object has no attribute 'isAlive'
=========================================================

PROPOSAL
~~~~~~~
From [|https://github.com/apache/kafka/blob/trunk/tests/docker/Dockerfile], we have:   "FROM openjdk:8"

• base image used to be based on Debian-10 earlier, now it seems to be updated to Debian-11

1. docker run openjdk:8 python3 -V
   Python 3.9.2    // python 3.9.2 doesn't support deprecated "isAlive" method, is_alive should be used

Deb-10 based image had python 3.7 which supports isAlive. python 3.8 is the last version to support it and deprecated for later python versions.
Making the is_alive change in "tests/kafkatest/services/monitor/http.py" allowed sysTests to continue.
=========================================================

 

Question to kafka SME
-------------------------
Do you believe this is a valid problem and the fix is acceptable?
Please let me know and I am happy to submit a PR.

 

Thanks.
