>                 Key: SPARK-26296
>                 URL: https://issues.apache.org/jira/browse/SPARK-26296
>             Project: Spark
>          Issue Type: Wish
>          Components: Spark Core
>    Affects Versions: 2.4.0
>            Reporter: M. Le Bihan
>            Priority: Minor
>
> I am not using _Scala_ when I am programming _Spark_ but plain _Java_. I believe those using _PySpark_ no more. 
>  
> But _Spark_ has been build over _Scala_ instead of plain _Java_ and this is a cause of troubles, especially at the time of upgrading the JDK. We are awaiting to use JDK 11 and _Scala_ is still lowering _Spark_ in the previous version of the JDK.
> _Big Data_ programming shall not force developpers to get by with _Scala_ when its not the language they have choosen.
>  
> Having a _Spark_ without _Scala_, like it is possible to have a _Spark_ without _Hadoop,_ would confort me : a cause of issues would disappear.
> Provide an optional _spark-scala_ artifact would be fine as those who do not need it wouldn't download it and wouldn't be affected by it.
