Eric Yang commented on YARN-8777:
---------------------------------
[~ebadger] {quote}Where do the shell expansion cases come from? We invoke the
docker binary using exec.{quote}
There is no shell expansion in this patch, but junior developer who interact
with docker exec from their terminal might not know that their command are
expanded by shell before docker exec is running.

> Since Container Executor provides Container execution using the native
> container-executor binary, we also need to make changes to accept new
> “dockerExec” method to invoke the corresponding native function to execute
> docker exec command to the running container.
