Class WordCountRemoteByClient

java.lang.Object

org.apache.flink.storm.wordcount.WordCountRemoteByClient

public class WordCountRemoteByClient
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 cluster similar to NimbusClient. The Flink cluster can be local or remote.

This example shows how to submit the program via 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: WordCountRemoteByClient <text path> <result path>
If no parameters are provided, the program is run with default data from WordCountData.

This example shows how to:

• submit a regular Storm program to a local or remote Flink cluster.
