[jira] [Commented] (YARN-10330) Add missing test scenarios to
TestUserGroupMappingPlacementRule and TestAppNameMappingPlacementRule
[ https://issues.apache.org/jira/browse/YARN-10330?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17149188#comment-17149188 ]

---------------------------------------
Hi [~pbacsko],
Can you please justify the UT failures?
I'm aware there are some flaky FS preemption tests out there, I guess [~mhudaky] reported a jira lately to fix those.
Anyway, it's better to link the jira(s) here.
In the meantime, I will check your patch.

> After running {{TestUserGroupMappingPlacementRule}} with EclEmma, it turned out that there are at least 8-10 missing test scenarios that are not covered.
> Since we're planning to enhance mapping rule logic with extra features, it is crucial to have good coverage so that we can verify backward compatibility.
