Subject IBM open-sources Spark Kernel
Date Fri, 12 Dec 2014 22:16:45 GMT



We are happy to announce a developer preview of the Spark Kernel which
enables remote applications to dynamically interact with Spark. You can
think of the Spark Kernel as a remote Spark Shell that uses the IPython
notebook interface to provide a common entrypoint for any application. The
Spark Kernel obviates the need to submit jars using spark-submit, and can
replace the existing Spark Shell.

You can try out the Spark Kernel today by installing it from our github
repo at https://github.com/ibm-et/spark-kernel. To help you get a demo
environment up and running quickly, the repository also includes a
Dockerfile and a Vagrantfile to build a Spark Kernel container and connect
to it from an IPython notebook.

We have included a number of documents with the project to help explain it
and provide how-to information:

* A high-level overview of the Spark Kernel and its client library (
https://issues.apache.org/jira/secure/attachment/12683624/Kernel%20Architecture.pdf
).

* README (https://github.com/ibm-et/spark-kernel/blob/master/README.md) -
building and testing the kernel, and deployment options including building
the Docker container and packaging the kernel.

* IPython instructions (
https://github.com/ibm-et/spark-kernel/blob/master/docs/IPYTHON.md) -
setting up the development version of IPython and connecting a Spark
Kernel.

* Client library tutorial (
https://github.com/ibm-et/spark-kernel/blob/master/docs/CLIENT.md) -
building and using the client library to connect to a Spark Kernel.

* Magics documentation (
https://github.com/ibm-et/spark-kernel/blob/master/docs/MAGICS.md) - the
magics in the kernel and how to write your own.

We think the Spark Kernel will be useful for developing applications for
Spark, and we are making it available with the intention of improving these
capabilities within the context of the Spark community (
https://issues.apache.org/jira/browse/SPARK-4605). We will continue to
develop the codebase and welcome your comments and suggestions.
