@Public
@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 PlacementConstraints (e.g., anti-affinity between Spark and HBase allocations). The size specification of the allocation is in ResourceSizing.
