[jira] [Created] (SPARK-30852) Use Long instead of Int as argument type in Dataset limit method

Damianos Christophides created SPARK-30852:
----------------------------------------------

             Summary: 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: Bug
          Components: Input/Output
    Affects Versions: 2.4.4
            Reporter: Damianos Christophides


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)?
