Hi Experts, I am very interesting that Hadoop could work with Docker and doing some trial on patch of YARN-1964.
I applied patch yarn-1964-branch-2.2.0-docker.patch of jira YARN-1964 on branch 2.2 and am going to install a Hadoop cluster using the new generated tarball including the patch. Then, I think I can use DockerContainerExecutor, but I do not know much details on the usage and have following questions: *1. After installation, What's the detailed config steps to adopt DockerContainerExecutor?* *2. How to verify whether a MR task is really launched in Docker container not Yarn container?* *3. Which hadoop branch will officially include Docker support?* Thanks a lot!
