Bernardo Gomez Palacio created SPARK-1522:
---------------------------------------------

             Summary: YARN ClientBase will throw a NPE if there is no YARN 
application specific classpath.
                 Key: SPARK-1522
                 URL: https://issues.apache.org/jira/browse/SPARK-1522
             Project: Spark
          Issue Type: Bug
          Components: YARN
    Affects Versions: 0.9.0, 1.0.0, 0.9.1
            Reporter: Bernardo Gomez Palacio
            Priority: Critical


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.
