Billie Rinaldi commented on YARN-4595: -------------------------------------- I think in the case of a mounted directory, symlinks inside the directory will be resolved inside the container (that is, they will not point to files outside the container). Does that seem like a problem? > Add support for configurable read-only mounts > --------------------------------------------- > > Key: YARN-4595 > URL: https://issues.apache.org/jira/browse/YARN-4595 > Project: Hadoop YARN > Issue Type: Sub-task > Components: yarn > Reporter: Billie Rinaldi > Assignee: Billie Rinaldi > Attachments: YARN-4595.1.patch, YARN-4595.2.patch, YARN-4595.3.patch, > YARN-4595.4.patch, YARN-4595.5.patch > > > Mounting files or directories from the host is one way of passing > configuration and other information into a docker container. We could allow > the user to set a list of mounts in the environment of ContainerLaunchContext > (e.g. /dir1:/targetdir1,/dir2:/targetdir2). These would be mounted read-only > to the specified target locations. > Due to permissions and user concerns, for this ticket we will require the > mounts to be resources that are in the distributed cache. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
