Constructs a
VertexRDDfrom an RDD of vertex-attribute pairs.Constructs a
VertexRDDfrom an RDD of vertex-attribute pairs. Duplicate vertex entries are merged usingmergeFunc. The resultingVertexRDDwill be joinable withedges, and any missing vertices referred to byedgeswill be created with the attributedefaultVal.- VD
the vertex attribute type
- vertices
the collection of vertex-attribute pairs
- edges
the EdgeRDD that these vertices may be joined with
- defaultVal
the vertex attribute to use when creating missing vertices
- mergeFunc
the commutative, associative duplicate vertex attribute merge function
