     [ https://issues.apache.org/jira/browse/YARN-5561?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Rohith Sharma K S updated YARN-5561:
------------------------------------
    Attachment: YARN-5561.02.patch

Updated the patch adding 2 more REST endpoints. 
One small difference is there in the REST endpoints for container i.e instead of */clusters/\{clusterid\}/apps/\{appid\}/appattempts/\{appattemptid\}/containers/\{contianer-id\}*,  I have changed to */clusters/\{clusterid\}/apps/\{appid\}/containers/\{contianer-id\}*.

> 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.
