Description

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
