Abin Shahab resolved YARN-2481.
    Resolution: Cannot Reproduce
      Assignee: Abin Shahab

Verified on trunk that JAVA_HOME can be set for containers(mappers and reducers 
for example), and that is not overridden by the NM's JAVA_HOME.

> YARN should allow defining the location of java

> Yarn right now uses the location of the JAVA_HOME on the host to launch 
> containers. This does not work with Docker containers which have their own 
> filesystem namespace and OS. If the location of the Java binary of the 
> container to be launched is configurable, yarn can launch containers that 
> have java in a different location than the host.
