-----------------------------

             Summary: TestNodeStatusUpdater#testNMRegistration incorrect
                 Key: YARN-1750
                 URL: https://issues.apache.org/jira/browse/YARN-1750
             Project: Hadoop YARN
          Issue Type: Bug
          Components: nodemanager
            Reporter: Ming Ma


This test case passes. However, the test output log has

java.lang.AssertionError: Number of applications should only be one! expected:<1> but was:<2>
        at org.junit.Assert.fail(Assert.java:93)
        at org.junit.Assert.failNotEquals(Assert.java:647)
        at org.junit.Assert.assertEquals(Assert.java:128)
        at org.junit.Assert.assertEquals(Assert.java:472)
        at org.apache.hadoop.yarn.server.nodemanager.TestNodeStatusUpdater$MyResourceTracker.nodeHeartbeat(TestNodeStatusUpdater.java:267)
        at org.apache.hadoop.yarn.server.nodemanager.NodeStatusUpdaterImpl$1.run(NodeStatusUpdaterImpl.java:469)
        at java.lang.Thread.run(Thread.java:695)

TestNodeStatusUpdater.java has invalid asserts.

      } else if (heartBeatID == 3) {
        // Checks on the RM end
        Assert.assertEquals("Number of applications should only be one!", 1,
            appToContainers.size());
        Assert.assertEquals("Number of container for the app should be two!",
            2, appToContainers.get(appId2).size());


We should fix the assert and add more check to the test.
