Subject [jira] [Created] (YARN-2109) TestRM fails some tests when some tests run with CapacityScheduler and some with FairScheduler
Date Wed, 28 May 2014 16:57:02 GMT
Anubhav Dhoot created YARN-2109:
-----------------------------------

             Summary: TestRM fails some tests when some tests run with CapacityScheduler and
some with FairScheduler
                 Key: YARN-2109
                 URL: https://issues.apache.org/jira/browse/YARN-2109
             Project: Hadoop YARN
          Issue Type: Bug
          Components: scheduler
            Reporter: Anubhav Dhoot


testNMTokenSentForNormalContainer requires CapacityScheduler and was fixed in [YARN-1846|https://issues.apache.org/jira/browse/YARN-1846]
to explicitly set it to be CapacityScheduler. But if the default scheduler is set to FairScheduler
then the rest of the tests that execute after this will fail with invalid cast exceptions
when getting queuemetrics. This is based on test execution order as only the tests that execute
after this test will fail. This is because the queuemetrics will be initialized by this test
to QueueMetrics and shared by the subsequent tests. 

We can explicitly clear the metrics at the end of this test to fix this.
For example

java.lang.ClassCastException: org.apache.hadoop.yarn.server.resourcemanager.scheduler.QueueMetrics
cannot be cast to org.apache.hadoop.yarn.server.resourcemanager.scheduler.fair.FSQueueMetrics
