Subject [jira] [Commented] (YARN-6930) Admins should be able to explicitly enable specific LinuxContainerRuntime in the NodeManager
Date Wed, 02 Aug 2017 20:39:02 GMT

    [ https://issues.apache.org/jira/browse/YARN-6930?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16111677#comment-16111677
] 

Miklos Szegedi commented on YARN-6930:
--------------------------------------

JavaSandboxLinuxContainerRuntime already works like this. See {{yarn.nodemanager.runtime.linux.sandbox-mode}}
for details. It is disabled by default. I suggest updating the title to DockerLinuxContainerRuntime
only.

> 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.
