Shane Kumpf commented on YARN-6930:
-----------------------------------
Thanks [~miklos.szeg...@cloudera.com] - I did notice how it is being used after
my comment. With the approach taken by JavaSandboxLinuxContainerRuntime, each
runtime is now responsible for providing configuration knobs to disable that
runtime. That means if the author of a new runtime forgets, there is no way to
explicitly disable that runtime. It seems a global runtime whitelist would
eliminate that concern, but having two configuration knobs isn't ideal either.
What is your preference?
> 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.
