> {{TestUserDefinedCounters.testMapReduceJob}} is flakey.  
> We sometimes see it fail:
> {noformat}
> junit.framework.AssertionFailedError
> 	at junit.framework.Assert.fail(Assert.java:48)
> 	at junit.framework.Assert.assertTrue(Assert.java:20)
> 	at junit.framework.Assert.assertTrue(Assert.java:27)
> 	at org.apache.hadoop.mapred.TestUserDefinedCounters.testMapReduceJob(TestUserDefinedCounters.java:113)
> {noformat}
> Upon investigation, the problem is that the input for the MR job in this test is at {{System.getProperty("test.build.data",
"/tmp") + "/input"}}.  If an earlier test wrote some files there, this test will use them
as part of its input.  This can cause all sorts of problems with this test because its not
expecting the additional input data.
