----
> Rework examples to use 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
> Labels: starter
>
> 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}
