Alejandro Abdelnur commented on MAPREDUCE-3370:
-----------------------------------------------
Ahmed, Instead using a System property, why don't you do JAR discovery by class?
JobConf has a findContainingJar() method that if you make it public would do
this for you:
The the code would be:
{{code}}
public class MiniMRYarnCluster extends MiniYARNCluster {
public static final String APPJAR
=JobConf.findContainingJar(LocalContainerLauncher.class);;
...
}
{{code}}
> MiniMRYarnCluster uses a hard coded path location for the MapReduce
> application jar

> MiniMRYarnCluster uses a hard coded relative path location for the MapReduce
> application jar. It is better to have this location as a system property so
> tests can pick the application jar regardless of their working directory.
