    Description

      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.

      [ERROR] testContainerLaunchWithCustomNetworks(org.apache.hadoop.yarn.server.nodemanager.containermanager.linux.runtime.TestDockerContainerRuntime)  Time elapsed: 0.411 s  <<< ERROR!
