Hitesh Shah commented on MAPREDUCE-3492:

Wordcount should now be part of hadoop-mapreduce-project/hadoop=mapreduce-examples/ which
is now part of the mavenized build.

> 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:
