[jira] [Created] (SPARK-4033) Input of the SparkPi too big causes the emption exception

hzw created SPARK-4033:
--------------------------

             Summary: Input of the SparkPi  too big causes the emption exception
                 Key: SPARK-4033
                 URL: https://issues.apache.org/jira/browse/SPARK-4033
             Project: Spark
          Issue Type: Bug
          Components: Examples
    Affects Versions: 1.2.0
            Reporter: hzw


If input of the SparkPi args is larger than the 25000, the integer 'n' inside the code will be overflow, and may be a negative number.
And it causes  the (0 until n) Seq as an empty seq, then doing the action 'reduce'  will throw the UnsupportedOperationException("empty collection").
