Subject [jira] [Commented] (YARN-6930) Admins should be able to explicitly enable specific LinuxContainerRuntime in the NodeManager
Date Tue, 29 Aug 2017 15:48:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-6930?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16145508#comment-16145508

Eric Badger commented on YARN-6930:

+  <property>
+    <name>yarn.nodemanager.runtime.linux.allowed-runtimes</name>
+    <value>DefaultLinuxContainerRuntime,DockerLinuxContainerRuntime</value>
+    <description>
+      Comma separated list of runtimes that are allowed when using
+      LinuxContainerExecutor.
+    </description>
+  </property>

We need to update this with the new enums.

Also, do we need a new file for the enum? Can we use LinuxContainerRuntimeConstants.java instead?

> 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.
