Huang Xingbo commented on FLINK-23493: -------------------------------------- [~gaoyunhaii] Thanks a lot for the reporting. I have tracked that Python process hangs in the progress of creating a child process. Similar problems have been reported in the Python community, but because there is no reproduction program provided, it is closed (https://bugs.python.org/issue39241 ). I am currently studying this part of the code of python subprocess.py. > python tests hang on Azure > -------------------------- > > Key: FLINK-23493 > URL: https://issues.apache.org/jira/browse/FLINK-23493 > Project: Flink > Issue Type: Bug > Components: API / Python > Affects Versions: 1.14.0, 1.13.1, 1.12.4, 1.15.0 > Reporter: Dawid Wysakowicz > Assignee: Huang Xingbo > Priority: Blocker > Labels: test-stability > Fix For: 1.15.0, 1.14.1 > > > https://dev.azure.com/apache-flink/apache-flink/_build/results?buildId=20898&view=logs&j=821b528f-1eed-5598-a3b4-7f748b13f261&t=4fad9527-b9a5-5015-1b70-8356e5c91490&l=22829 -- This message was sent by Atlassian Jira (v8.20.1#820001)
