java.lang.Object

org.apache.flink.graph.examples.ConnectedComponents

All Implemented Interfaces:

org.apache.flink.api.common.ProgramDescription

public class ConnectedComponents
extends Object
implements org.apache.flink.api.common.ProgramDescription

This example shows how to use Gelly's library methods. You can find all available library methods in org.apache.flink.graph.library. In particular, this example uses the GSAConnectedComponents library method to compute the connected components of the input graph. The input file is a plain text file and must be formatted as follows: Edges are represented by tuples of srcVertexId, trgVertexId which are separated by tabs. Edges themselves are separated by newlines. For example: 1\t2\n1\t3\n defines two edges, 1-2 with and 1-3. Usage ConnectedComponents <edge path> <result path> <number of iterations>
If no parameters are provided, the program is run with default data from ConnectedComponentsDefaultData
