Subject [jira] [Commented] (YARN-6930) Admins should be able to explicitly enable specific LinuxContainerRuntime in the NodeManager
Date Mon, 30 Oct 2017 16:47:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-6930?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16225289#comment-16225289
] 

Varun Vasudev commented on YARN-6930:
-------------------------------------

[~djp], this change turns off the Docker runtime by default. It has to be explicitly turned
on in 2.9. In 2.8 it was turned on by default .Given that the Docker work is alpha, it may
not be necessary, but I just wanted to make sure.

> 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.
