Project: SystemML
Issue Type: Bug
Components: Runtime

Reporter: Greg Senia
When attempting to execute the following task via SystemML using the YARN
ApplicationMaster it is not sourcing Hadoop's JAVA_HOME it is taking whatever
is defined in the OS $PATH variable throwing the error below. The solution is
to use the YARN function: Environment.JAVA_HOME.$$() + "/bin/java".
