Wangda Tan commented on YARN-7612:
----------------------------------
Thanks [~asuresh].
The latest patch looks much better.
I haven't checked any details yet, quick comments about organizations of code
packages.
Here's my proposal:
{code}
constraint/
api/ (btw what is spi? is it a typo?):
Algorithm
SchedulingProposalCollector
SchedulingRequestHandler
SchedulingResponseHandler
PlacementAlgorithmOutput
PlacedSchedulingRequest
SchedulingResponse
impl/
PlacementDispatcher
PlacementProcessor
SamplePlacementAlgorithm
algorithms/sample/:
BatchedRequests
SamplePlacementAlgorithm
NodeCandidateSelector
<rest things like>:
PlacementConstraintsManager
PlacementConstraintsManagerImpl
AllocationTagsManager
AllocationTagsNamespaces
InvalidAllocationTagsQueryException
{code}
In addition, do you think we should move api and impl packages to
{{scheduler.constraint}}? To me it is part of scheduler instead of being part
of "placement". Same for reservation as well.

> This introduces a Placement Processor and a Planning algorithm framework to
> handle placement constraints and scheduling requests from an app and places
> them on nodes.
> The actual planning algorithm(s) will be handled in a YARN-7613.
