-------------------------------------
Summary: CapacityScheduler test TestUserGroupMappingPlacementRule
should build proper hierarchy
Key: YARN-10277
URL: https://issues.apache.org/jira/browse/YARN-10277
Project: Hadoop YARN
Issue Type: Task
Reporter: Gergely Pollak
Since the CapacityScheduler internal implementation depends more and more on
queue being hierarchical, the test gets really hard to maintain. A lot of test
cases were failing because they used non existing queues, but the older
placement rule solution ignored missing parents, but since the leaf queue
change in CS, we must be able to get a full path for any queue, since all
queues are referenced by their full path.
This test should reflect this and instead of creating and expecting the
existance of fictional queues, it should create a proper queue hierarchy, with
a way to describe it better.
Currently we set up a bunch of mockito "when" statements to simulate the queue
behavior, but this is a hassle to maintain, and easy to miss a few method.
