----------------------------------
Summary: Capacity scheduler: add support for combined %user +
%primary_group mapping
Key: YARN-9841
URL: https://issues.apache.org/jira/browse/YARN-9841
Project: Hadoop YARN
Issue Type: Improvement
Components: capacity scheduler
Reporter: Peter Bacsko
Assignee: Peter Bacsko
Right now in CS, using {{%primary_group}} with a parent queue is only possible
this way:
{{u:%user:parentqueue.%primary_group}}
Looking at
https://github.com/apache/hadoop/blob/trunk/hadoop-yarn-project/hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-resourcemanager/src/main/java/org/apache/hadoop/yarn/server/resourcemanager/placement/UserGroupMappingPlacementRule.java,
we cannot do something like:
{{u:%user:%primary_group.%user}}
Fair Scheduler supports a nested rule where such a placement/mapping rule is
possible. This improvement would reduce this feature gap.
