[jira] [Commented] (YARN-6387) Provide a flag in Rest API GET response to notify if the app launch delay is due to docker image download.

    [ https://issues.apache.org/jira/browse/YARN-6387?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16227789#comment-16227789 ] 

Eric Yang commented on YARN-6387:
---------------------------------

Do we still need this?  There is no description.  The current REST API only response the final result.  If the goal is to provide progress during REST API call to create containers, then we probably need to add extension to the REST API.  Each of the operation (create, start, stop, flex) can be reference by an operation ID.  Front end can invoke REST API with operation ID to inspect the current progress of the operation.  Without operation centric API, it is not possible to determine if container is in downloading state or container is started and running.
