mapreduce examples jar is not built properly
--------------------------------------------

                 Key: MAPREDUCE-3492
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-3492
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: examples
            Reporter: Ravi Gummadi


When I try to build examples jar using "ant -Dresolvers=internal examples" in trunk, the jar
created in build/ directory is of very small size, may be empty jar. And trying to run wordcount
job gives the error:

Exception in thread "main" java.lang.ClassNotFoundException: org.apache.hadoop.examples.ExampleDriver
