Shane Kumpf commented on YARN-5258: ----------------------------------- Sorry for the very late response here. Overall, this looks great. Thanks [~templedf] for putting this together! 1) {code} When the LCE launches YARN a container to execute in a Docker container, the application can specify the Docker images to be used with that YARN container. {code} It seems removing the first occurrence of YARN would make this clearer, or consider shortening. 2) {code} In order to launch Docker containers, the Docker daemon be running on all NodeManager hosts where Docker containers will be launched. {code} "...the Docker daemon *must* be running..." 3) {code} Note that the Java and Hadoop versions must be compatible with what’s installed on the cluster. {code} I'm not sure what this means exactly. Can you help clarify a bit in the docs? 4) Connecting to a Secure Docker Repository - Unfortunately, I don't believe the default of $HOME/.docker/config.json will work in the implicit pull scenario. It seems $HOME is not expanded in container-executor when running the Docker client commands. Given this, we should advise that it is necessary to pre-pull images from private registries and that implicit pulls from private registries are not supported without YARN-5428. > Document Use of Docker with LinuxContainerExecutor > -------------------------------------------------- > > Key: YARN-5258 > URL: https://issues.apache.org/jira/browse/YARN-5258 > Project: Hadoop YARN > Issue Type: Sub-task > Components: documentation > Affects Versions: 2.8.0 > Reporter: Daniel Templeton > Assignee: Daniel Templeton > Priority: Critical > Labels: oct16-easy > Attachments: YARN-5258.001.patch, YARN-5258.002.patch, > YARN-5258.003.patch, YARN-5258.004.patch > > > There aren't currently any docs that explain how to configure Docker and all > of its various options aside from reading all of the JIRAs.
