Spark as a Library
Hello,
Suppose I want to use Spark from an application that I already submit to run in another container (e.g. Tomcat). Is this at all possible? Or do I have to split the app into two components, and submit one to Spark and one to the other container? In that case, what is the preferred way for the two components to communicate with each other? Thanks!
Best, Oliver

You can create a new SparkContext inside your container pointed to your
master. However, for your script to run you must call addJars to put the
code on your workers' classpaths (except when running locally).
Hopefully your webapp has some lib folder which you can point to as a
source for the jars. In the Play Framework you can use
play.api.Play.application.getFile("lib") to get a path to the lib directory
and get the contents. Of course that only works on the packaged web app.

Hi,
Spark job server by ooyala is the right tool for the job. It exposes rest api so calling it from a web app is suitable.
Is open source, you can find it on github

Oggetto: RE: Spark as a Library
Hello,
Thanks for the response and great to hear it is possible. But how do I connect to Spark without using the submit script?
I know how to start up a master and some workers and then connect to the master by packaging the app that contains the SparkContext and then submitting the package with the spark-submit script in standalone-mode. But I don’t want to submit the app that contains the SparkContext via the script, because I want that app to be running on a web server. So, what are other ways to connect to Spark? I can’t find in the docs anything other than using the script. Thanks!

If you want to run the computation on just one machine (using Spark's local mode), it can probably run in a container. Otherwise you can create a SparkContext there and connect it to a cluster outside. Note that I haven't tried this though, so the security policies of the container might be too restrictive. In that case you'd have to run the app outside and expose an RPC interface between them.

It depends on what you want to do with Spark. The following has worked for
me.
Let the container handle the HTTP request and then talk to Spark using
another HTTP/REST interface. You can use the Spark Job Server for this.
Embedding Spark inside the container is not a great long term solution IMO
because you may see issues when you want to connect with a Spark cluster.
