Rohith Sharma K S commented on YARN-5561:
-----------------------------------------

As of now /apps cab be dropped since apps can be retrieved using flows. Based on the use case from UI let us decide the /apps at cluster level.

> ATSv2 model lacks retrieval of {{list-of-all-apps}}, {{list-of-all-app-attempts}} and {{list-of-all-containers-per-attempt}} via REST API's. And also it is required to know about all the entities in an applications.
> It is pretty much highly required these URLs for Web  UI.
> New REST URL would be 
> # GET {{/ws/v2/timeline/apps}}
> # GET {{/ws/v2/timeline/apps/\{app-id\}/appattempts}}.
> # GET {{/ws/v2/timeline/apps/\{app-id\}/appattempts/\{attempt-id\}/containers}}
> # GET {{/ws/v2/timeline/apps/\{app id\}/entities}} should display list of entities that can be queried.
