-------------------------------------

             Summary: PySpark take() does not launch a Spark job when it has to
                 Key: SPARK-1839
                 URL: https://issues.apache.org/jira/browse/SPARK-1839
             Project: Spark
          Issue Type: Bug
          Components: PySpark
    Affects Versions: 1.0.0
            Reporter: Hossein Falaki


If you call take() or first() on a large FilteredRDD, the driver attempts to scan all partitions to find the first valid item. If the RDD is large this would fail or hang.
