> Hadoop currently supports one JVM defined through JAVA_HOME.
> Since multiple JVMs (Java 6,7,8,9) are active, it will be helpful if there is an user configuration to choose the custom but supported JVM for her job.
> In other words, user will be able to choose her expected JVM only for her container execution while Hadoop services may be running on different JVM.
