Package com.intel.hadoop.graphbuilder.preprocess.mapreduce

Class Summary
CreateGraphMapper The Mapper class parses each input value provided by the InputFormat, and outputs a list of Vertex and a list of Edge using a GraphTokenizer.
CreateGraphMR This MapReduce Job creates an initial edge list and vertex list from raw input data, e.g.
CreateGraphReducer The Reducer class applies user defined Functionals to reduce duplicate edges and vertices.
EdgeTransformCombiner<VidType extends WritableComparable<VidType>> Combine the intermediate key value pairs.
EdgeTransformMapper<VidType extends WritableComparable<VidType>> This Mapper class maps each edge (u,v,data) into (u, (v, data)) or (v, (u, data)) based on reduceEndPoint parameter in the JobConf configured in EdgeTrandFormMR.
EdgeTransformMR This MapReduce Class applies user defined "Reduce" and "Apply" functional on edges that share the same source or target vertex, determined by the reduceEndPoint parameter.
EdgeTransformReducer<VidType extends WritableComparable<VidType>> The Reduce functional computes a sufficient statistics on a list of edges, and the Apply functional applies it back to each edge in the list.
