Description

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.
