    Why is this deprecated?


> 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.
