-------------------------------------
Summary: CapacityScheduler incorrect User Group Mapping after leaf
queue change
Key: YARN-10254
URL: https://issues.apache.org/jira/browse/YARN-10254
Project: Hadoop YARN
Issue Type: Bug
Reporter: Gergely Pollak
Assignee: Gergely Pollak
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.
