Hi Shivaram,
If the Apache code is calling to GPLd (v2) code, then there is an incompati= bility issue. [Apache v2 & GPL v2 does not have compatibility]

Nevertheles= s, GPL v3 have compatibility with Apache v2. [only in certain cases]

It is the other way around: the GPLv3= people claims that Apache v2 code cannot be bundled with GPLv2, but can wi= th GPLv3.

No GPLed code can be incorporated into Apache code with= out forcing Apache to release its codebase as GPL. See=C2=A0http://www.apache.org/leg= al/resolved.html#category-x

Hi

I am Shivaram Venkataraman, a committer on the Apache Spark project.
Recently we have been working on developing an R interface to Spark
which allows users to run R code on Spark. In this context, we have a
licensing related question that we would like some help with.

The R interface to Spark (SparkR) uses rJava, a GPL-licensed
third-party R package that presents functions to communicate from R to
Java. =C2=A0In the SparkR code, rJava is simply imported into the R
workspace through an "include" command, and is not shipped in eit= her
source or binary form with SparkR. Further the R code in SparkR (and
the R code we call into in rJava) is not linked but interpreted by R.

We would like to merge SparkR as a part of the Apache Spark project
and distribute it similar to our Python frontend. From what we can see
there exist other R packages like rmr2 (an R interface to Apache
Hadoop [1]) and Myrrix (an R interface to Apache Mahout [2]) that
provide Apache licensed code, while depending on GPL packages to
bridge from R to other large scale execution engines. However we were
wondering if there are any restrictions in Apache license of calling
into GPL code through a scripting language that we should be aware of.

Please let us know if you need any further details.

Thanks
Shivaram
