Class RunPageRankSchimmy

java.lang.Object
  org.apache.hadoop.conf.Configured
      edu.umd.cloud9.example.pagerank.RunPageRankSchimmy

All Implemented Interfaces:

Configurable, Tool

public class RunPageRankSchimmy
extends Configured
implements Tool

Main driver program for running the Schimmy implementation of PageRank. Command-line arguments are as follows:

• [basePath]: the base path
• [numNodes]: number of nodes in the graph
• [start]: starting iteration
• [end]: ending iteration
• [useCombiner?]: 1 for using combiner, 0 for not
• [useInMapCombiner?]: 1 for using in-mapper combining, 0 for not
• [useRange?]: 1 for range partitioning, 0 for not

The starting and ending iterations will correspond to paths /base/path/iterXXXX and /base/path/iterYYYY. As a example, if you specify 0 and 10 as the starting and ending iterations, the driver program will start with the graph structure stored at /base/path/iter0000; final results will be stored at /base/path/iter0010.
