Subject [jira] [Created] (YARN-4578) Directories that are mounted in docker containers need to be more restrictive/container-specific
Date Mon, 11 Jan 2016 22:40:39 GMT
Sidharta Seethana created YARN-4578:
---------------------------------------

             Summary: Directories that are mounted in docker containers need to be more restrictive/container-specific
                 Key: YARN-4578
                 URL: https://issues.apache.org/jira/browse/YARN-4578
             Project: Hadoop YARN
          Issue Type: Sub-task
            Reporter: Sidharta Seethana
            Assignee: Sidharta Seethana


Currently, the "top level" log and local directories are mounted inside docker containers
(see below for an example). This is not restrictive enough - we need to ensure that only container
specific directories are mounted.
