Takashi Ohnishi commented on YARN-4566:
---------------------------------------
The test failed with another cause...
The stack trace is the same with YARN-4453
{code}
java.lang.Exception: test timed out after 60000 milliseconds
at java.lang.Thread.sleep(Native Method)

org.apache.hadoop.io.retry.RetryInvocationHandler.invoke(RetryInvocationHandler.java:158)

org.apache.hadoop.yarn.server.TestMiniYarnClusterNodeUtilization.testUpdateNodeUtilization(TestMiniYarnClusterNodeUtilization.java:113)
{code}
And also the TestContainerManagerSecurity failed with the same error reported
by YARN-4342
