Jason Lowe commented on YARN-6930:
----------------------------------
Thanks for the 2.8 patch!
I don't understand why updateEnvForWhitelistVars has been updated to throw
ContainerExecutionException when it isn't that way in trunk or branch-2. For
consistency with the trunk/branch-2 code it should be consistent. See
DelegatingLinuxContainerRuntime#updateEnvForWhitelistVars in branch-2 for
reference. Once that exception declaration is removed then the
TestContainerLaunch changes should also drop out of the patch.
> 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.
