Can you convert the Scala code into a `HadoopInputs` as well?
> Deprecate Hadoop dependent methods in flink-java
> ------------------------------------------------
>
> Key: FLINK-4315
> URL: https://issues.apache.org/jira/browse/FLINK-4315
> Project: Flink
> Issue Type: Task
> Components: Java API
> Reporter: Stephan Ewen
> Assignee: Evgeny Kincharov
> Fix For: 2.0.0
>
>
> The API projects should be independent of Hadoop, because Hadoop is not an
> integral part of the Flink stack, and we should have the option to offer
> Flink without Hadoop dependencies.
> The current batch APIs have a hard dependency on Hadoop, mainly because the
> API has utility methods like `readHadoopFile(...)`.
> I suggest to deprecate those methods and add helpers in the
> `flink-hadoop-compatibility` project.
> FLINK-4048 will later remove the deprecated methods.
