Arun C Murthy commented on YARN-2481:
-------------------------------------
[~ashahab] YARN already allows the JAVA_HOME to be overridable... take a look
at {{ApplicationConstants.Environment.JAVA_HOME}} and
{{YarnConfiguration.DEFAULT_NM_ENV_WHITELIST}} for the code-path.
> 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.
