Varun Saxena commented on YARN-4224:
------------------------------------
bq. For UID based queries we can pass type as a query parameter. For the
hierarchical endpoints, type is modeled as a part of entity ids (we have to do
this to uniquely id an entity).
IIUC, you mean that we can have endpoint as /ws/v2/timeline/apps/\{app
UID\}/entities?entityType=... for UID
and,
endpoint as /ws/v2/timeline/apps/\{app UID\}/entities/\{entitytype\} for
hierarchical REST URL.
Lets reach an agreement on this then
Frankly a query without entity type wont be very useful, but lets do this for
differentiation. Any issues in making a check for entityType not being supplied
though(other than that it is a query param) ? Currently query without entity
type is not supported. Some changes, although minor, will have to be made in
storage layer for this.
