We made this adjustment because the unit tests `TestAMWebApp#testMRWebAppSSLEnabled` and `TestAMWebApp#testMRWebAppSSLEnabledWithClientAuth` are failing in JUnit 5. In the original JUnit 4 environment, these tests relied on the `EnvironmentVariables.set` method to modify `System.Env` data. However, in JUnit 5, we can no longer modify the environment variables directly. One important reason for this is that starting from JDK 9, `System.Env` became an immutable structure. It is recommended to use `System.setProperty` and `System.getProperty` as replacements. Therefore, we modified the unit tests to temporarily set `System.setProperty`, and also check if the variables we set exist in `System.getProperty` when used. > Upgrade Junit 4 to 5 in hadoop-mapreduce-client-app > --------------------------------------------------- > > Key: MAPREDUCE-7418 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-7418 > Project: Hadoop Map/Reduce > Issue Type: Sub-task > Components: test > Affects Versions: 3.3.4 > Reporter: Ashutosh Gupta > Assignee: Ashutosh Gupta > Priority: Major > Labels: pull-request-available > > Upgrade Junit 4 to 5 in hadoop-mapreduce-client-app -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: mapreduce-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: mapreduce-issues-h...@hadoop.apache.org
