Charo Zhang commented on YARN-8986:
-----------------------------------
[~eyang] I know what your mean, it will use bridge network as default network
type if ''--net" option don't exist for docker run. But in my opinion:
the default network is controlled by
yarn.nodemanager.runtime.linux.docker.default-container-network for Yarn
Docker, we should't consider Docker default network type. That's mean when
network name is not specified( it 's same to "net" is null in command_config),
it's better to use
yarn.nodemanager.runtime.linux.docker.default-container-network value or add
"--net=none".
> publish all exposed ports to random ports when using bridge network
