Class WordCountLocalByName

java.lang.Object

org.apache.flink.storm.wordcount.WordCountLocalByName

public class WordCountLocalByName
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 and submitted to Flink for execution in the same way as to a Storm LocalCluster. In contrast to WordCountLocal all bolts access the field of input tuples by name instead of index.

This example shows how to run program directly within Java, thus it cannot be used to submit a StormTopology via Flink command line clients (ie, bin/flink).

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

Usage: WordCountLocalByName <text path> <result path>
If no parameters are provided, the program is run with default data from WordCountData.

This example shows how to:

• run a regular Storm program locally on Flink
