JIRA: [HDFS-16106](https://issues.apache.org/jira/browse/HDFS-16106) This unit test occasionally fails. The value set for dfs.namenode.accesstime.precision is too low, result in the execution of the method, accesstime could be set many times, eventually leading to failed assert. IMO, dfs.namenode.accesstime.precision should be greater than or equal to the timeout(120s) of TestDFSShell#testCopyCommandsWithPreserveOption(), or directly set to 0 to disable this feature. ```[ERROR] Tests run: 52, Failures: 3, Errors: 0, Skipped: 0, Time elapsed: 106.778 s <<< FAILURE! - in org.apache.hadoop.hdfs.TestDFSShell [ERROR] testCopyCommandsWithPreserveOption(org.apache.hadoop.hdfs.TestDFSShell) Time elapsed: 2.353 s <<< FAILURE! java.lang.AssertionError: expected:<1625095098319> but was:<1625095099374> at org.junit.Assert.fail(Assert.java:89) at org.junit.Assert.failNotEquals(Assert.java:835) at org.junit.Assert.assertEquals(Assert.java:647) at org.junit.Assert.assertEquals(Assert.java:633) at org.apache.hadoop.hdfs.TestDFSShell.testCopyCommandsWithPreserveOption(TestDFSShell.java:2282) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:59) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:12) at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:56) at org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:17) at org.junit.internal.runners.statements.FailOnTimeout$CallableStatement.call(FailOnTimeout.java:299) at org.junit.internal.runners.statements.FailOnTimeout$CallableStatement.call(FailOnTimeout.java:293) at java.util.concurrent.FutureTask.run(FutureTask.java:266) at java.lang.Thread.run(Thread.java:748) [ERROR] testCopyCommandsWithPreserveOption(org.apache.hadoop.hdfs.TestDFSShell) Time elapsed: 2.467 s <<< FAILURE! java.lang.AssertionError: expected:<1625095192527> but was:<1625095193950> at org.junit.Assert.fail(Assert.java:89) at org.junit.Assert.failNotEquals(Assert.java:835) at org.junit.Assert.assertEquals(Assert.java:647) at org.junit.Assert.assertEquals(Assert.java:633) at org.apache.hadoop.hdfs.TestDFSShell.testCopyCommandsWithPreserveOption(TestDFSShell.java:2323) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:59) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:12) at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:56) at org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:17) at org.junit.internal.runners.statements.FailOnTimeout$CallableStatement.call(FailOnTimeout.java:299) at org.junit.internal.runners.statements.FailOnTimeout$CallableStatement.call(FailOnTimeout.java:293) at java.util.concurrent.FutureTask.run(FutureTask.java:266) at java.lang.Thread.run(Thread.java:748) [ERROR] testCopyCommandsWithPreserveOption(org.apache.hadoop.hdfs.TestDFSShell) Time elapsed: 2.173 s <<< FAILURE! java.lang.AssertionError: expected:<1625095196756> but was:<1625095197975> at org.junit.Assert.fail(Assert.java:89) at org.junit.Assert.failNotEquals(Assert.java:835) at org.junit.Assert.assertEquals(Assert.java:647) at org.junit.Assert.assertEquals(Assert.java:633) at org.apache.hadoop.hdfs.TestDFSShell.testCopyCommandsWithPreserveOption(TestDFSShell.java:2303) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:59) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:12) at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:56) at org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:17) at org.junit.internal.runners.statements.FailOnTimeout$CallableStatement.call(FailOnTimeout.java:299) at org.junit.internal.runners.statements.FailOnTimeout$CallableStatement.call(FailOnTimeout.java:293) at java.util.concurrent.FutureTask.run(FutureTask.java:266) at java.lang.Thread.run(Thread.java:748)``` -- This is an automated message from the Apache Git Service.
