        The full log looks like this

        MultiFileWordCount failed
        
        junit.framework.AssertionFailedError: MultiFileWordCount failed
        	at org.apache.hadoop.mapreduce.TestMapReduceLocal.runMultiFileWordCount(TestMapReduceLocal.java:183)
        	at org.apache.hadoop.mapreduce.TestMapReduceLocal.testWithLocal(TestMapReduceLocal.java:91)
        

        The assertion message states the obvious, but doesn't help in the failure analysis.
