> Timeline reader provides REST end point for querying app with an URL {{GET /ws/v2/timeline/apps/\{app id\}}} along with queryParam as an filter. But queryParam such as {{userId/flowname/flowrunid}} not at useful for querying an app with app-id. In YARN cluster, only one app-id will be exist though out life time. So userId/flowname/flowrunid not at all useful for the app-id REST empoint
