----------------------------------------------
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)?
