Class WordCountTopology

java.lang.Object

org.apache.flink.storm.wordcount.WordCountTopology

public class WordCountTopology
extends Object

Implements the "WordCount" program that computes a simple word occurrence histogram over text files in a streaming fashion. The program is constructed as a regular StormTopology.

The input is a plain text file with lines separated by newline characters.

Usage: WordCount[Local|LocalByName|RemoteByClient|RemoteBySubmitter] <text path> <result path>
If no parameters are provided, the program is run with default data from WordCountData.

This example shows how to:
