-------------------------------------------
I published a pull request that address this issue. It contains documentation,
that explains how one can use Groovy, and examples, that demonstrate the
usefulness of Groovy for Spark.
> Groovy bindings for Spark
> -------------------------
>
> Key: SPARK-2171
> URL: https://issues.apache.org/jira/browse/SPARK-2171
> Project: Spark
> Issue Type: Improvement
> Components: Build, Documentation, Examples
> Affects Versions: 1.0.0
> Reporter: Artur Andrzejak
> Priority: Minor
> Attachments: Groovy4Spark - Introduction.pdf, Groovy4Spark starter
> kit.zip, examples-Groovy4Spark.zip
>
>
> A simple way to add Groovy bindings to Spark, without additional code.
> The idea is to use the standard java implementations of RDD and
> Context and to use the coercion of Groovy closure to abstract classes
> to call all methods, which take anonymous inner classes in Java, with a
> closure.
> Advantages:
> - No need for new code, which avoids unnecessary bugs and implementation
> effort
> - Access to spark from Groovy with the ease of closures using the
> default Java implementations
> - No need to install additional software
