[~cloud_fan] [~dongjoon] long value can be used as limit expression in presto
and postgresql. I think spark should also allow long values for limit
expression.

> Project: Spark
> Issue Type: Improvement
> Components: SQL
> 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)?
