Jian He updated YARN-5430:
--------------------------
Attachment: YARN-5430.1.patch
What the patch does:
- For docker container: container-executable runs the docker inspect (which
already runs today to get the pid) to get the hostname and ip address. NM
stores that in container status to let app query.
- For regular container: simply return local host ip and address.
> Get container's ip and host from NM

> In YARN-4757, we introduced a DNS mechanism for containers. That's based on
> the assumption that we can get the container's ip and host information and
> store it in the registry-service. This jira aims to get the container's ip
> and host from the NM, primarily docker container
