             Summary: Add a flag to use local docker image instead of getting latest from registry
                 Key: YARN-8955
                 URL: https://issues.apache.org/jira/browse/YARN-8955
             Project: Hadoop YARN
          Issue Type: Sub-task
            Reporter: Eric Yang


Some companies have security policy to use local docker images instead of getting latest images from internet.  When docker image is pulled in localization phase, there are two possible out comes.  The image is getting the latest from trusted registries, or the image is a static local copy.  This task is to add a configuration flag to give priority to local image over trusted registry image. 
 If a image already exist locally, node manager does not trigger docker pull to get the latest image from trusted registries.
