Gergo Repas commented on YARN-8268:
-----------------------------------
When only applying the test changes (in TestAllocationFileLoaderService) to
current trunk and running this test, the following assertion fails:
{code:java}
java.lang.AssertionError: reservable queue should not be a parent queue
at org.junit.Assert.fail(Assert.java:88)
at org.junit.Assert.assertTrue(Assert.java:41)
at org.junit.Assert.assertFalse(Assert.java:64)
at
org.apache.hadoop.yarn.server.resourcemanager.scheduler.fair.TestAllocationFileLoaderService.testReservableQueue(TestAllocationFileLoaderService.java:811)
at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
...
{code}
This demonstrates the problem with the current allocation file processing. The
rest of the changes in the attached patch addresses this issue.
