----------------------------------
Summary: Capacity scheduler: add support for Secondary Group user
mapping
Key: YARN-9840
URL: https://issues.apache.org/jira/browse/YARN-9840
Project: Hadoop YARN
Issue Type: Improvement
Reporter: Peter Bacsko
Assignee: Peter Bacsko
Currently, Capacity Scheduler only supports primary group rule mapping like
this:
{{u:%user:%primary_group}}
Fair scheduler already supports secondary group placement rule. Let's add this
to CS to reduce the feature gap.
