Gergely Pollak commented on YARN-10254:
---------------------------------------
[~pbacsko] thank you for the feedbacks, the additional logging is indeed a good
idea, uploaded the next patch, I still expect some tests to fail, since
YARN-10108 isn't merged yet on which we depend on it but want to run a a new
round because on my machine I saw a few flaky tests and I wonder if it is a
local issue, or I've introduced new issues with the logging (I doubt it, but
it's better to be on the safe side)

> Key: YARN-10254
> URL: https://issues.apache.org/jira/browse/YARN-10254
> Project: Hadoop YARN
> Issue Type: Bug
> Reporter: Gergely Pollak
> Assignee: Gergely Pollak
> Priority: Major
> Attachments: YARN-10254.001.patch, YARN-10254.002.patch,
> YARN-10254.003.patch, YARN-10254.004.patch

>
> YARN-9879 and YARN-10198 introduced some major changes to user group mapping,
> and some of them unfortunately had some negative impact on the way mapping
> works.
> In some cases incorrect PlacementContexts were created, where full queue path
> was passed as leaf queue name. This affects how the yarn cli app list
> displays the queues.
> u:%user:%primary_group.%user mapping fails with an incorrect validation error
> when the %primary_group parent queue was a managed parent.
> Group based rules in certain cases are mapped to root.[primary_group] rules,
> loosing the ability to create deeper structures.
