link3280 opened a new pull request #6616: [FLINK-10218] Allow writing DataSet
without explicit path parameter
URL: https://github.com/apache/flink/pull/6616
## What is the purpose of the change
Add an file output helper method, which requires only FileOutputFormat
parameter, to DataSet API. This can avoid setting duplicate path parameters,
since the output path could be found in FileOutputFormat.
## Brief change log
- *Add an file output helper method, which requires only FileOutputFormat
parameter, to DataSet API.*
## Verifying this change

> Allow writing DataSet without explicit path parameter
> -----------------------------------------------------
>
> Key: FLINK-10218
> URL: https://issues.apache.org/jira/browse/FLINK-10218
> Project: Flink
> Issue Type: Improvement
> Components: DataSet API
> Affects Versions: 1.6.0
> Reporter: Paul Lin
> Priority: Minor
> Labels: pull-request-available
>
> Currently, DataSet API has two overloaded `write` methods for using
> FileOutputFormat as output format, and both require a path parameter, but the
> output path could already be set in the FileOutputFormat object. What's more,
> the subclasses of FileOutputFormat mostly don't have default constructors and
> required a path parameter too, so users have to set output path twice in the
> code, like:
> {code:java}
> String output = "hdfs:///tmp/";
> dataset.write(new TextOutputFormat<>(new Path(output)), output);
> {code}
> So I propose to add another write helper method that requires no path
> parameter. May someone assign this issue to me?
