---------------------------------

             Summary: Property docker.trusted.registries does not work when using a list
                 Key: YARN-8783
                 URL: https://issues.apache.org/jira/browse/YARN-8783
             Project: Hadoop YARN
          Issue Type: Bug
    Affects Versions: 3.1.1
            Reporter: Simon Prewo


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*:

docker.trusted.registries=centos

But having *a list of trusted registries configured fails* ("Shell error output: image: centos is not trusted."):

docker.trusted.registries=centos,ubuntu
