These container that run user code can contain the specific libraries that the application needs, and they can have different versions of Perl,python or even Java than the NodeManager. In fact, these container can run different versions of Linux than the NodeManager OS. Although Yarncontainer must define all the environments and libraries required to run the job, none of the things in NodeManager are shared.
