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.

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!
