GitHub user 397090770 opened a pull request:
https://github.com/apache/spark/pull/9734
[SPARK-11751]Doc describe error in the "Spark Streaming Programming Guide"
page
In the **[Task Launching
Overheads](http://spark.apache.org/docs/latest/streaming-programming-guide.html#task-launching-overheads)**
section,
>Task Serialization: Using Kryo serialization for serializing tasks can
reduce the task sizes, and therefore reduce the time taken to send them to the
slaves.
as we known **Task Serialization** is configuration by
**spark.closure.serializer** parameter, but currently only the Java serializer
is supported. If we set **spark.closure.serializer** to
**org.apache.spark.serializer.KryoSerializer**, then this will throw a
exception.
