---------------------------------

             Summary: TestDockerContainerRuntime test failures due to UID lookup of a non-existent user
                 Key: YARN-7810
                 URL: https://issues.apache.org/jira/browse/YARN-7810
             Project: Hadoop YARN
          Issue Type: Bug
         Environment: YARN-7782 enabled the Docker runtime feature to remap the username to uid:gid form for launching Docker containers. The feature does an {{id -u}} and {{id -G}} to get the UID and GIDs. This fails with the test user, as that user doesn't actually exist on the host.
