Sidharta Seethana commented on YARN-4266: ----------------------------------------- [~tangzhankun], please feel free to take this over. Do you have a proposal for dealing with logs, directories etc? > Allow whitelisted users to disable user re-mapping/squashing when launching > docker containers > --------------------------------------------------------------------------------------------- > > Key: YARN-4266 > URL: https://issues.apache.org/jira/browse/YARN-4266 > Project: Hadoop YARN > Issue Type: Sub-task > Components: yarn > Reporter: Sidharta Seethana > Assignee: Sidharta Seethana > > Docker provides a mechanism (the --user switch) that enables us to specify > the user the container processes should run as. 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
