Shane Kumpf commented on YARN-6930:
-----------------------------------
Thanks for the feedback [~jlowe] and [~ebadger]. I have uploaded a new patch to
address the comments. Runtime types are now represented as an enum, docs have
been updated with allowed values, and the runtimes will no longer be
instantiated or initialized if the runtime is not allowed.
> Admins should be able to explicitly enable specific LinuxContainerRuntime in
> the NodeManager

> Today, in the java land, all LinuxContainerRuntimes are always enabled when
> using LinuxContainerExecutor and the user can simply invoke anything that
> he/she wants - default, docker, java-sandbox.
> We should have a way for admins to explicitly enable only specific runtimes
> that he/she decides for the cluster. And by default, we should have
> everything other than the default one disabled.
