CLASSPATH fails for YARN application master

I am developing on a 4 node cluster using HDP 184.108.40.206.0.6.0-76 on CentOS 6. And I have developed a YARN application that is built on the distributed shell example. The example works fine when running on a single node cluster.
When I submit the YARN application from a remote machine, then I get a “class not found” exception for a yarn configuration class because the classpath for the application master does not include the yarn jar files.
On the 4 node cluster the “yarn.application.classpath” is properly configured and includes all of the correct directories. It looks like this:
However, the system property “java.class.path” in the application master does not have the “yarn.application.classpath” entries included in it and so the required yarn classes are not found.
How can I set the classpath correctly to include the entries from “yarn.application.classpath”?
Thanks for any pointers or help.
