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

Modifier and Type	Method	Description
static PlacementConstraint.AbstractConstraint	PlacementConstraints.cardinality(java.lang.String scope, int minCardinality, int maxCardinality, java.lang.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(java.lang.String scope, java.lang.String namespace, int minCardinality, int maxCardinality, java.lang.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(java.lang.String scope, int maxCardinality, java.lang.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(java.lang.String scope, java.lang.String tagNamespace, int maxCardinality, java.lang.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(java.lang.String scope, int minCardinality, java.lang.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(java.lang.String scope, java.lang.String namespace, int minCardinality, java.lang.String... allocationTags)	Similar to PlacementConstraints.minCardinality(String, int, String...), but let you attach a namespace to the allocation tags.
static PlacementConstraint.AbstractConstraint	PlacementConstraints.targetCardinality(java.lang.String scope, int minCardinality, int maxCardinality, PlacementConstraint.TargetExpression... targetExpressions)	This constraint generalizes the cardinality and target constraints.
static PlacementConstraint.AbstractConstraint	PlacementConstraints.targetIn(java.lang.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(java.lang.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(java.lang.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.
