@InterfaceAudience.Public @InterfaceStability.Unstable public abstract class SchedulingRequest extends Object
SchedulingRequest
represents a request made by an application to the
ResourceManager
to obtain an allocation. It is similar to the
ResourceRequest
. However, it is more complete than the latter, as it
allows applications to specify allocation tags (e.g., to express that an
allocation belongs to Spark
or is an HBase-master
), as well
as involved PlacementConstraint
s (e.g., anti-affinity between Spark
and HBase allocations).
The size specification of the allocation is in ResourceSizing
