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 java8-tests/test
For Maven users,

Maven users can also refer to their Java 8 directory using JAVA_HOME.

$ JAVA_HOME=/opt/jdk1.8.0/ mvn clean install -DskipTests $ JAVA_HOME=/opt/jdk1.8.0/ mvn -pl :java8-tests_2.11 test

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.
