-----------------------------------------------------------------------
[~hitesh] We would be sending 14 requests.
1. Query ATS for 10+1(For pagination) tasks
2. Load app details from RM for status correction / If not available then AHS.
3. Load DAG from ATS for getting the Vertex Name
4. Now DAG have a dependency on AHS for queue, so automatically that also gets
loaded. This must go away once we start using TEZ-3267. The app details from #2
could be used for DAG's status correction.
5. And finally the new requests. For each task with an attempt, a separate
request would be send, and the result returned would be cached at the page
level.
- Agree that the number of attempt requests might look high. But the other
option would be to load all the attempts in parallel to the tasks.
