Methods in org.apache.hadoop.yarn.api.resource that return PlacementConstraint.AbstractConstraint

Modifier and Type	Method	Description
static PlacementConstraint.AbstractConstraint	PlacementConstraints.cardinality(String scope, int minCardinality, int maxCardinality, String... allocationTags)	Creates a constraint that restricts the number of allocations within a given scope (e.g., node or rack).
static PlacementConstraint.AbstractConstraint	PlacementConstraints.cardinality(String scope, String namespace, int minCardinality, int maxCardinality, String... allocationTags)	Similar to PlacementConstraints.cardinality(String, int, int, String...), but let you attach a namespace to the given allocation tags.
PlacementConstraint.AbstractConstraint	PlacementConstraint.TimedPlacementConstraint.getConstraint()	Get the constraint that has to be satisfied within the time window.
PlacementConstraint.AbstractConstraint	PlacementConstraint.getConstraintExpr()	Get the constraint expression of the placement constraint.
static PlacementConstraint.AbstractConstraint	PlacementConstraints.maxCardinality(String scope, int maxCardinality, String... allocationTags)	Similar to PlacementConstraints.cardinality(String, int, int, String...), but determines only the maximum cardinality (the minimum cardinality is 0).
static PlacementConstraint.AbstractConstraint	PlacementConstraints.maxCardinality(String scope, String tagNamespace, int maxCardinality, String... allocationTags)	Similar to PlacementConstraints.maxCardinality(String, int, String...), but let you specify a namespace for the tags, see supported namespaces in AllocationTagNamespaceType.
static PlacementConstraint.AbstractConstraint	PlacementConstraints.minCardinality(String scope, int minCardinality, String... allocationTags)	Similar to PlacementConstraints.cardinality(String, int, int, String...), but determines only the minimum cardinality (the maximum cardinality is unbound).
static PlacementConstraint.AbstractConstraint	PlacementConstraints.minCardinality(String scope, String namespace, int minCardinality, String... allocationTags)	Similar to PlacementConstraints.minCardinality(String, int, String...), but let you attach a namespace to the allocation tags.
static PlacementConstraint.AbstractConstraint	PlacementConstraints.targetCardinality(String scope, int minCardinality, int maxCardinality, PlacementConstraint.TargetExpression... targetExpressions)	This constraint generalizes the cardinality and target constraints.
static PlacementConstraint.AbstractConstraint	PlacementConstraints.targetIn(String scope, PlacementConstraint.TargetExpression... targetExpressions)	Creates a constraint that requires allocations to be placed on nodes that satisfy all target expressions within the given scope (e.g., node or rack).
static PlacementConstraint.AbstractConstraint	PlacementConstraints.targetNodeAttribute(String scope, NodeAttributeOpCode opCode, PlacementConstraint.TargetExpression... targetExpressions)	Creates a constraint that requires allocations to be placed on nodes that belong to a scope (e.g., node or rack) that satisfy any of the target expressions based on node attribute op code.
static PlacementConstraint.AbstractConstraint	PlacementConstraints.targetNotIn(String scope, PlacementConstraint.TargetExpression... targetExpressions)	Creates a constraint that requires allocations to be placed on nodes that belong to a scope (e.g., node or rack) that does not satisfy any of the target expressions.
