Amos commented on SPARK-10183:
------------------------------
Pushed code up last night to link R to a running spark context. I'm not able to
post a link from my iPhone but it's in elbamos/incubator-Zeppelin, branch
reinterpreter, and the code you'll care about is in classes RContext (which
does the work), RBackendHelper (because the Backend is private) and RStatics.
> Expose the SparkR backend api

> Key: SPARK-10183
> URL: https://issues.apache.org/jira/browse/SPARK-10183
> Project: Spark
> Issue Type: Improvement
> Components: SparkR
> Reporter: Amos
> Priority: Minor
>
> The Backend class is currently scoped to the api.r package. I'm accessing it,
> for the Zeppelin project, so I can start SparkR against an already-running
> spark context. To do this I've had to create a helper class withing api.r. It
> would be better if the backend were exposed. It isn't a tremendous amount of
> functionality - create a backend, start it, stop it.
> (If we want to be really clever, it could also be passed a spark context and
> make that available to R clients, facilitate passing rdd's back and forth,
> etc. I'll be pushing code that does some of that to Zeppelin in a day or two
> if that helps.)
