Wonderdog with Hadoop2/YARN #20

I compiled Pig to use Hadoop2.2.0 and installed ElasticSearch and Wonderdog. Running a Pig job in this setup fails with the following error:

"java.lang.IncompatibleClassChangeError: Found interface org.apache.hadoop.mapreduce.TaskAttemptContext, but class was expected
at org.apache.hadoop.mapred.LocalJobRunner$Job.run(LocalJobRunner.java:403)"

I was wondering if there is way to build Wonderdog for it to work with Hadoop2/YARN.

Thanks

I was able to get rid of this kind of error by recreating the Wonderdog project with the dependency in the pom.xml file updated. Change the artifact id to "hadoop-client" and the version to "2.2.0."
