["Stamatis Zampetakis (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/IMPALA-14925?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=18076345#comment-18076345 ] 

Stamatis Zampetakis commented on IMPALA-14925:
----------------------------------------------

Initially, I thought that the whole migration can be completed with a few hours of work but it turned out a bit more complex than expected. Not sure if I will be able to find time to bring this to completion but in order not to lose the effort done so far I plan to share shortly some findings and progress from my first attempt.

> The JUnit4 release line is in maintenance mode with the last release ([4.13.2|https://github.com/junit-team/junit4/releases/tag/r4.13.2]) dating back in Feb 13, 2021. This task is about migrating to the latest actively maintained release line that at this point in time is [6.0.3|https://github.com/junit-team/junit-framework/releases/tag/r6.0.3]. 
> Although it is feasible to use JUnit4 and JUnit6 at the same time through the vintage test engine in practice various issues arise when used in conjunction with some plugins such as [Maven Surefire Plugin|https://maven.apache.org/surefire/maven-surefire-plugin/]. 
> Given that the number of Java based tests are not using many exotic features, opting for a full migration of JUnit4 to JUnit6, i.e., dropping entirely the JUnit4 dependencies, is more advantageous and would simplify future maintenance.
> The migration guide can be found here: https://docs.junit.org/6.0.3/migrating-from-junit4.html
