             Summary: Add support for setting the PID namespace mode
                 Key: YARN-7729
                 URL: https://issues.apache.org/jira/browse/YARN-7729
             Project: Hadoop YARN
          Issue Type: Sub-task
          Components: nodemanager
            Reporter: Shane Kumpf


Docker has support for allowing containers to share the PID namespace with the host or other containers via the {{--pid}} {{docker run}} flag.

There are a number of use cases where this is desirable:
* Monitoring tools running in containers that use process IDs.
* Debug containers that can attach to another container to run strace, gdb, etc.
* Testing Docker on YARN in a container, where the docker socket is bind mounted.

Enabling this feature should be considered privileged as it exposes host details inside the container.
