Subject [jira] [Commented] (YARN-6930) Admins should be able to explicitly enable specific LinuxContainerRuntime in the NodeManager
Date Mon, 30 Oct 2017 20:01:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-6930?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16225652#comment-16225652

Junping Du commented on YARN-6930:

bq. It has to be explicitly turned on in 2.9. In 2.8 it was turned on by default.
If so, I agree that we should mark this fix in 2.9 as incompatible in case users upgrade from
2.8 to 2.9 with assumption that docker runtime is on by default.

> 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.
