Eric Yang commented on YARN-7654:
---------------------------------
[~jlowe] Yes, you are right patch 001 doesn't handle shell expansion, and
likely to cause more problems if release schedule happened prior to having a
chance to close all holes. I am going to stay on course for execv version. It
is a bit late for me to restart the coding to fix execv problem first then
apply entry_point after. I think it is possible to get this done within 50k of
code changes.

> Docker image may have ENTRY_POINT predefined, but this is not supported in
> the current implementation. It would be nice if we can detect existence of
> {{launch_command}} and base on this variable launch docker container in
> different ways:
> h3. Launch command exists
> {code}
> docker run [image]:[version]
> docker exec [container_id] [launch_command]
> {code}
> h3. Use ENTRY_POINT
> {code}
> docker run [image]:[version]
> {code}
