All Implemented Interfaces:

Configurable, Tool

public class DemoCountClueWarcRecords
extends Configured
implements Tool

Simple demo program to count the number of records in the ClueWeb09 collection, from either the original source WARC files or repacked SequenceFiles (controlled by the first command-line parameter). The program also verifies the docid to docno mappings.

The program takes four command-line arguments:

• [original|repacked]: which version? 'original' for original source WARC files; 'repacked' for SequenceFiles
• [base-path]: base path of the ClueWeb09 distribution or base path of the SequenceFiles
• [segment-num]: segment number (1 through 10)
• [mapping-file]: docno mapping data file

Here's a sample invocation:

 hadoop jar cloud9.jar edu.umd.cloud9.collection.clue.DemoCountSourceClueWarcRecords \
   original /umd/collections/ClueWeb09 1 /umd/collections/ClueWeb09/docno-mapping.dat
