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

The findbugs warning is unrelated to this patch. YARN-7034 addressed the 
warning for trunk and branch-2, but it appears this was missed in the 
branch-2.8 patch. I'll open a new JIRA to address this in branch-2.8 and 
branch-2.8.2.

> 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.
