Mohammad Kamrul Islam commented on YARN-2481:
---------------------------------------------

Very good to know that [~acmurthy].

Just to confirm my understanding:  So user can override JAVA_HOME for "each job". right? 

I assume it is through job conf?

> 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.
