Subject [jira] [Commented] (YARN-6930) Admins should be able to explicitly enable specific LinuxContainerRuntime in the NodeManager
Date Thu, 03 Aug 2017 17:48:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-6930?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16113170#comment-16113170
] 

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

Thanks [~miklos.szegedi@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?

> 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.
