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 Functional s 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. |
