Class AdjacencyMatrixJob
java.lang.Object
org.apache.hadoop.conf.Configured
org.apache.mahout.common.AbstractJob
org.apache.mahout.graph.AdjacencyMatrixJob
- All Implemented Interfaces:
- org.apache.hadoop.conf.Configurable, org.apache.hadoop.util.Tool
public class AdjacencyMatrixJob
- extends AbstractJob
Distributed computation of the adjacency matrix of a graph, see http://en.wikipedia.org/wiki/Adjacency_matrix
This job outputs SequenceFile
s an IntWritable
as key and a VectorWritable
as value
Command line arguments specific to this class are:
- --output=(path): output path where the resulting matrix and the number of vertices should be written
- --vertices=(path): file containing a list of all vertices
- --edges=(path): Directory containing edges of the graph
- --symmetric = (boolean) produce a symmetric adjacency matrix (corresponds to an undirected graph)
General command line options are documented in AbstractJob
.
Note that because of how Hadoop parses arguments, all "-D" arguments must appear before all other arguments.
