{quote}I thought the goal is to not have to depend on YARN in the first place.

Don't see that mention anywhere in this Jira.
APEX is very tightly coupled to YARN. It is a YARN application that uses the
YARN abstractions. Decoupling from YARN will be a substantial effort for APEX.
The description says
{quote}This will be particularly helpful when applications depend on native,
non-JVM packages like Python and R, that otherwise need to be installed
separately.
{quote}
YARN supports running docker containers, which is via YARN-3611, it will be
helpful for running dockerized APEX operators. This, in my opinion, is easier
and faster to accomplish.

> Project: Apache Apex Core
> Issue Type: New Feature
> Reporter: Thomas Weise
> Priority: Major
> Labels: roadmap
>
> Apex should support deployment using Docker as alternative to application
> packages. Docker images provide a simple and standard way to package
> dependencies and solve isolation from the host environment. This will be
> particularly helpful when applications depend on native, non-JVM packages
> like Python and R, that otherwise need to be installed separately. Docker
> support will also be a step towards supporting other cluster managers like
> Kubernetes, Mesos and Swarm.
