> I am deploying the default yarn distributed shell example:
> {code:java}
> yarn jar hadoop-yarn-applications-distributedshell.jar -shell_env YARN_CONTAINER_RUNTIME_TYPE=docker -shell_env YARN_CONTAINER_RUNTIME_DOCKER_IMAGE=centos -shell_command "sleep 90" -jar hadoop-yarn-applications-distributedshell.jar -num_containers 1{code}
> Having a *single trusted registry configured like this works*:
> {code:java}
> docker.trusted.registries=centos{code}
> But havingĀ *a list of trusted registries configured fails* ("Shell error output: image: centos is not trusted."):
> {code:java}
> docker.trusted.registries=centos,ubuntu{code}
