Jason Lowe commented on YARN-7654:
----------------------------------
{quote}On Mac, it doesn't function the same for key value pair that are quoted.
{quote}
There's no need to quote values if we're using the envfile approach, right?
{quote}When specified both --env-file and -e, the evaluation order is env file
then -e.
{quote}
Why would be be specifying both arguments? All of the environment variables
would go into the envfile.
{quote}Another concern is the ENV file is in the localizer directory, and job
submitter can call identical filename to override the file.
{quote}
The file would go into the nmPrivate directory which is not accessible by the
user, only writable by the NM user and would be read by the container-executor.
This is the same location where the NM writes the launch script and tokens
today to be picked up by the container-executor. The user would not be able to
access or overwrite this file.

> 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}
