> Project: Hadoop Map/Reduce
> Issue Type: Bug

> {{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.
