[jira] [Created] (YARN-2480) DockerContainerExecutor must support user namespaces

Abin Shahab created YARN-2480:
---------------------------------

             Summary: DockerContainerExecutor must support user namespaces
                 Key: YARN-2480
                 URL: https://issues.apache.org/jira/browse/YARN-2480
             Project: Hadoop YARN
          Issue Type: New Feature
            Reporter: Abin Shahab


When DockerContainerExector launches a container, the root inside that container has root privileges on the host. 
This is insecure in a mult-tenant environment. The uid of the container's root user must be mapped to a non-privileged user on the host.
