Sunil Govindan commented on YARN-7863:
--------------------------------------
Attached rebased patch.
[~cheersyang], these constraints are treated as independently in scheduler. For
each request on the lookup node, we can check the placement request which is
demanded. And if multiple constraints are made on one requests, it will be
checked sequentially. Current design is inline with placement spec design what
is done. But i think AND mapped to : might have created a bit of confusion.
