Rohith Sharma K S commented on YARN-5561:
-----------------------------------------
Other option is publish the entities as string rather than object. The below
one is info value holds as object.
{code}
"SYSTEM_INFO_PARENT_ENTITY": {
"type": "YARN_APPLICATION",
"id": "application_1471931266232_0024"
}
{code}
This can split into below which is very much useful in filtering.
{code}
"SYSTEM_INFO_PARENT_ENTITY_TYPE": "YARN_APPLICATION"
"SYSTEM_INFO_PARENT_ENTITY_ID":"application_1471931266232_0024"
{code}

>
> 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.
