Eric Yang commented on YARN-7654:
---------------------------------
[~jlowe][~ebadger][~Jim_Brennan][~shaneku...@gmail.com] Thank you all for your
feedbacks. It looks like almost majority of people involved are agreeing to do
--env-file approach, and I will revise the patch for proposal #2. There is
zero chance of shell expansion with execvp. The stdout.txt command line output
is only a render of what the command looks like. Ps and top will display
argv[0] as command. It will not display any -e parameters. Unless people
change their mind, I consider env matter closed and move forward with the
implementation.

> 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}
