Bryan Cutler 31921e0f0b [SPARK-4557][STREAMING] Spark Streaming foreachRDD Java API method should accept a VoidFunction<...> 
Currently streaming foreachRDD Java API uses a function prototype requiring a return value of null.  This PR deprecates the old method and uses VoidFunction to allow for more concise declaration.  Also added VoidFunction2 to Java API in order to use in Streaming methods.  Unit test is added for using foreachRDD with VoidFunction, and changes have been tested with Java 7 and Java 8 using lambdas.

Java 8 Test Suites

These tests require having Java 8 installed and are isolated from the main Spark build. If Java 8 is not your system's default Java version, you will need to point Spark's build to your Java location. The set-up depends a bit on the build system:

  • Sbt users can either set JAVA_HOME to the location of a Java 8 JDK or explicitly pass -java-home to the sbt launch script. If a Java 8 JDK is detected sbt will automatically include the Java 8 test project.

    $ JAVA_HOME=/opt/jdk1.8.0/ build/sbt clean "test-only org.apache.spark.Java8APISuite"

  • For Maven users,

    Maven users can also refer to their Java 8 directory using JAVA_HOME. However, Maven will not automatically detect the presence of a Java 8 JDK, so a special build profile -Pjava8-tests must be used.

    $ JAVA_HOME=/opt/jdk1.8.0/ mvn clean install -DskipTests $ JAVA_HOME=/opt/jdk1.8.0/ mvn test -Pjava8-tests -DwildcardSuites=org.apache.spark.Java8APISuite

    Note that the above command can only be run from project root directory since this module depends on core and the test-jars of core and streaming. This means an install step is required to make the test dependencies visible to the Java 8 sub-project.
