> Use Long instead of Int as argument type in Dataset limit method
> ----------------------------------------------------------------
>
> Key: SPARK-30852
> URL: https://issues.apache.org/jira/browse/SPARK-30852
> Project: Spark
> Issue Type: Improvement
> Components: Input/Output
> Affects Versions: 2.4.4
> Reporter: Damianos Christophides
> Priority: Minor
>
> The Dataset limit method takes an input of type Int, which is a 32bit integer. The numerical upper limit of this type is 2,147,483,647. I found in my work to need to apply a limit to a Dataset higher than that which gives an error:
> "py4j.Py4JException: Method limit([class java.lang.Long]) does not exist"
>
> Could the input type of the limit method be changed to a Long (64bit)?
