Will add unit tests and re-base to trunk when we got agreement. was (Author: tangzhankun): A patch based on branch-2.8 for your reference.

We use this mechanism today > when launching docker containers . In non-secure mode, we run the docker > container based on > `yarn.nodemanager.linux-container-executor.nonsecure-mode.local-user` and in > secure mode, as the submitting user. However, this mechanism breaks down with > a large number of 'pre-created' images which don't necessarily have the users > available within the image. Examples of such images include shared images > that need to be used by multiple users. We need a way in which we can allow a > pre-defined set of users to run containers based on existing images, without > using the --user switch. There are some implications of disabling this user > squashing that we'll need to work through : log aggregation, artifact > deletion etc., -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
