      Description

      Thread.sleep() function is called to wait for NodeManager to identify disk failures. But in some cases, for example the lower-end hardware computer, the sleep time is too short so that the NodeManager may haven't finished identifying disk failures. This will occur test errors:

      	Running org.apache.hadoop.yarn.server.TestDiskFailures
      	Tests run: 3, Failures: 2, Errors: 0, Skipped: 0, Time elapsed: 17.686 sec <<< FAILURE! - in org.apache.hadoop.yarn.server.TestDiskFailures
      	testLocalDirsFailures(org.apache.hadoop.yarn.server.TestDiskFailures)  Time elapsed: 10.412 sec  <<< FAILURE!
      	java.lang.AssertionError: NodeManager could not identify disk failure.
      			at org.junit.Assert.fail(Assert.java:88)
      			at org.junit.Assert.assertTrue(Assert.java:41)
      			at org.apache.hadoop.yarn.server.TestDiskFailures.verifyDisksHealth(TestDiskFailures.java:239)
      			at org.apache.hadoop.yarn.server.TestDiskFailures.testDirsFailures(TestDiskFailures.java:186)
      			at org.apache.hadoop.yarn.server.TestDiskFailures.testLocalDirsFailures(TestDiskFailures.java:99)
      
      	testLogDirsFailures(org.apache.hadoop.yarn.server.TestDiskFailures)  Time elapsed: 5.99 sec  <<< FAILURE!
      	java.lang.AssertionError: NodeManager could not identify disk failure.
      			at org.junit.Assert.fail(Assert.java:88)
      			at org.junit.Assert.assertTrue(Assert.java:41)
      			at org.apache.hadoop.yarn.server.TestDiskFailures.verifyDisksHealth(TestDiskFailures.java:239)
      			at org.apache.hadoop.yarn.server.TestDiskFailures.testDirsFailures(TestDiskFailures.java:186)
      			at org.apache.hadoop.yarn.server.TestDiskFailures.testLogDirsFailures(TestDiskFailures.java:111)
      
      

      So extend the sleep time from 1000ms to 1500ms to avoid some unit test errors.
