Subramaniam Krishnan updated YARN-1708:
---------------------------------------
Attachment: YARN-1708.patch
Thanks [~vinodkv] for taking the time to review and for the follow up
discussions. I am uploading a new API patch based on the consensus we reached.
The summary of the changes are:
- Make all proto fields as optional, with default and add server side code to
check for required fields.
- Rename ReservationCreateRequestProto -> ReservationSubmissionRequestProto
- Rename ReservationDescriptionProto -> ReservationRequestsProto
- Rename ReservationResourceRequestProto -> ReservationRequestsProto
- Added a new ReservationRequestProto which will be specifically to specify
resources to reserve instead of reusing ResourceRequestProto as currently
reservations does not use locality constraints. In future we see convergence of
both.
- Rename ReservationDescriptionInterpreterProto ->
ReservationRequestInterpreterProto. Added examples for each reservation type in
Javadoc.
- ReservationHandle is not needed.
- Add ReservationIdProto: ClusterTimeStamp + long id : Similar to appIDs
- Rename ReservationCreateResponseProto -> ReservationSubmissionResponseProto
- ReservationUpdateRequestProto: No need to pass queue-name
-- Instead should specify ReservationID and the effect will be to replace the
existing reservation with new one.
- ReservationUpdateResponseProto: Can just be empty
- Add a ReservationDeleteRequestProto with ReservationId which will be deleted
- ReservationDeleteResponseProto: again can just be empty
> Add a public API to reserve resources (part of YARN-1051)
