]
Peter Bacsko updated YARN-10103:
Description:
You can't ask Capacity Scheduler for a mapping to create a queue if it doesn't
exist.
For example, this mapping would use the first rule if the queue exist. If it
doesn't, then it proceeds to the next rule:
{{u:%user:%primary_group.%user:create=false;u:%user%:root.default}}
Let's say user "alice" belongs to the "admins" group. It would first try to map
{{root.admins.alice}}. But, if the queue doesn't exist, then it places the
application into {{root.default}}.
