Xin Ren 21a6dd2aef [SPARK-16535][BUILD] In pom.xml, remove groupId which is redundant definition and inherited from the parent
https://issues.apache.org/jira/browse/SPARK-16535

## What changes were proposed in this pull request?

When I scan through the pom.xml of sub projects, I found this warning as below and attached screenshot
```
Definition of groupId is redundant, because it's inherited from the parent
```

I've tried to remove some of the lines with groupId definition, and the build on my local machine is still ok.
```
<groupId>org.apache.spark</groupId>
```
As I just find now `<maven.version>3.3.9</maven.version>` is being used in Spark 2.x, and Maven-3 supports versionless parent elements: Maven 3 will remove the need to specify the parent version in sub modules. THIS is great (in Maven 3.1).

## How was this patch tested?

I've tested by re-building the project, and build succeeded.

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.
