Thanks Roman for getting back to me so quickly. I checked with Cloudera and=
 they have a maven repository for CDH5 (version 2.2.0-cdh5.0.0-beta-2) as s=
hown below:

<repository>
      <id>cloudera</id>
      <url>https://repository.cloudera.com/artifactory/cloudera-repos/</url=
>
</repository>

I added that to the pom.xml file and ran a new build using the following co=
mmand:

mvn -Phadoop_yarn -Dhadoop.version=3D2.2.0-cdh5.0.0-beta-2 clean package -D=
skipTests

The program now gets further, but throws the following exception:

Do you have any additional suggestions for what I should try?

Thanks for your help.

It may help to build against CDH5 directly by:
   * manually adding repository.cloudera.com to the set of repos
   * specifying -Dhadoop.version=3D2.2.0-cdh5.0.0-beta-2

You need to provide way more logs from the YARN side for us to make sense o=
f it.

Thanks,
Roman.
