-------------------------------------
Summary: Rework examples to use new ParameterTool
Key: FLINK-2021
URL: https://issues.apache.org/jira/browse/FLINK-2021
Project: Flink
Issue Type: Improvement
Components: Examples
Affects Versions: 0.9
Reporter: Robert Metzger
Priority: Minor
In FLINK-1525, we introduced the {{ParameterTool}}.
We should port the examples to use the tool.
The examples could look like this (we should maybe discuss it first on the
mailing lists):
{code}
public static void main(String[] args) throws Exception {
ParameterTool pt = ParameterTool.fromArgs(args);
boolean fileOutput = pt.getNumberOfParameters() == 2;
String textPath = null;
String outputPath = null;
if(fileOutput) {
textPath = pt.getRequired("input");
outputPath = pt.getRequired("output");
}
// set up the execution environment
final ExecutionEnvironment env =
ExecutionEnvironment.getExecutionEnvironment();
env.getConfig().setUserConfig(pt);
{code}
