Description

The current implementation of ClientBase.getDefaultYarnApplicationClasspath inspects the MRJobConfig class for the field DEFAULT_YARN_APPLICATION_CLASSPATH when it should be really looking into YarnConfiguration.

If the Application Configuration has no yarn.application.classpath defined a NPE exception will be thrown.
