There's also some interesting ideas coming up around other languages and Big Data on the JVM, especially in
functional programming. People are finding ways to use FP languages like
Clojure and
Scala for Big Data processing, taking advantage of features that support parallelism, streaming etc. And the
Map-Reduce model is itself inspired by well-established concepts in FP. So I think there are lots of interesting opportunities available to make good use of the JVM in Big Data applications, even going beyond the current Java/Hadoop mainstream.
