> This is similar to [MAPREDUCE-103] . We should pass a whitelisted set of environment variables from NM env to the container. By default, we should pass HADOOP_* variables. This can be a simple configuration key that NodeManager reads.
> Today, we already either pass the following correctly or assume that it works but doesn't
>  - YARN_HOME: ContainerLaunch#writeLaunchEnv
>  - HADOOP_CLIENT_OPTS: MapReduceChildJVM#setVMEnv
>  - JAVA_HOME: TaskAttemptImpl#createContainerLaunchContext - Works by shell-expansion.
>  - LD_LIBRARY_PATH: Assumed to work via shell-expansion but doesn't.
