Hi,
I'm testing a sample code and I get this error. Here is the sample code I use :
scala> import org.apache.spark.streaming._
import org.apache.spark.streaming._
scala> def mappingFunction(key: String, value: Option[Int], state: State[Int]):
Option[String] = {
| Option(key)
| }
mappingFunction: (key: String, value: Option[Int], state:
org.apache.spark.streaming.State[Int])Option[String]
scala> val spec = StateSpec.function(mappingFunction)
<console>:41: error: missing arguments for method mappingFunction;
follow this method with `_' if you want to treat it as a partially applied
function
val spec = StateSpec.function(mappingFunction)
^
I followed the current documentation
https://spark.apache.org/docs/1.6.1/api/java/org/apache/spark/streaming/StateSpec.html
Any idea ?
