Description

Running this test several times (e.g. 30), it fails ~5-10 times.

Stacktrace: 

java.lang.AssertionError at org.junit.Assert.fail(Assert.java:86) at org.junit.Assert.assertTrue(Assert.java:41) at org.junit.Assert.assertTrue(Assert.java:52) at org.apache.hadoop.yarn.server.nodemanager.containermanager.container.TestContainer.testKillOnNew(TestContainer.java:594)

TestContainer:594 is the following code in trunk, currently:

Assert.assertTrue( containerMetrics.finishTime.value() > containerMetrics.startTime .value());

So sometimes the finish time is not greater than the start time.
