Shane Kumpf commented on YARN-6930:
-----------------------------------

Thanks for the feedback, [~jlowe]! I'm not opposed to moving this to enums and simpler names
if that is the preferred direction.

If we are going the hardcoded route then arguably we should list the ones we know about here
so users know what they can do.

When you say "list the ones we know about here", can you elaborate on what you mean? List
them in the documentation?

> 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.
