             Summary: Require Java 8 for Spark 2.x
                 Key: SPARK-14347
                 URL: https://issues.apache.org/jira/browse/SPARK-14347
             Project: Spark
          Issue Type: Task
          Components: MLlib, Spark Core, SQL, Streaming
    Affects Versions: 2.0.0
            Reporter: Sean Owen


Putting this down as a JIRA to advance the discussion -- I think this is far enough along to consensus for that.

The change here is to require Java 8. This means:

- Require Java 8 in the build
- Only build and test with Java 8, removing other older Jenkins configs
- Remove MaxPermSize
- Remove reflection to use Java 8-only methods
- Move external/java8-tests to core/streaming and remove profile

And optionally:

- Update all Java 8 code to take advantage of 8+ features, like lambdas, for simplification
