Subject [jira] [Commented] (YARN-5394) Correct the wrong file name when mounting /etc/passwd to Docker Container
Date Wed, 27 Jul 2016 07:59:20 GMT

    [ https://issues.apache.org/jira/browse/YARN-5394?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15395195#comment-15395195

Zhongyue Luo commented on YARN-5394:
------------------------------------

If we aren't going to mount /etc/passwd then I agree we should remove all attempts of mounting
it and fix the user issue in 5360

> Current LCE (DockerLinuxContainerRuntime) is mounting /etc/passwd to the container. But
it seems to use wrong file name "/etc/password" for container.
> {panel}
> .addMountLocation("/etc/passwd", "/etc/password:ro");
> {panel}
> This causes LCE failed to launch the Docker container if the Docker images don't create
the same user name and UID in it.
