How to import a class from a jar?

[tribbloid]

I'm trying to combine it with Apache Spark (one of the hottest framework for data analysis) but I don't know how to do it. Can someone give me a hint so I can possibly implement it myself? Of course, if someone is still maintaining this project.

I think you only need to add it to the kernel dependencies

scala-notebook/project/build.scala

Line 101 in 98eecbc

libraryDependencies ++= Seq(

Tribbloid, I'm trying to get it working with spark as well. Adding it to the kernel allows you to import it, but I'm still running into issues because scala notebook uses akka 2.1.4, while spark 1.0 uses akka 2.2.3. If you get it working, I'd love to hear about it, and I'll do the same.

Hi Tyler,

Thanks a lot! I'm not a proficient sbt user but I've encounter another jar hell problem in maven: http://apache-spark-user-list.1001560.n3.nabble.com/Spark-throws-NoSuchFieldError-when-testing-on-cluster-mode-td8064.html#a8083

The solution in maven is to include maven-shade plugin and rename the akka package in the notebook (since spark-shell will always load himself first). I'll fork this repo and migrate to maven in a few days.

I'm not sure if sbt-assembly has a similar switch that can do this. Perhaps it worths a try :)

Yours Peng

I tried upgrading to akka 2.2 but had trouble with the remote forking. Maybe I'll try it again.

Hi all, I'm going to give this a try. However, I would prefer to catch up where you guyz are. Is there any sample repo from where I can go ahead?
Thanks in advance

So I started an integration... the hard way, but works quite fine: https://github.com/andypetrella/scala-notebook/tree/spark

Any doc to get it working with Spark?

[andypetrella]

I'll try to put some doc in the README, and most probably a blog, however the changes are quite deep and will be hard (non trivial) to migrate back :-(

I gave this one a try https://github.com/andypetrella/scala-notebook/tree/spark but it couldn't compile the code. See the image below

To not pollute this entry, could you fill an issue on the repo? Although this is not a compilation error but a (AFAICS) a misusage of sbt.
There are several manner to use it, the longer but safer:

sbt
project server
run

The fastest:

sbt server/run
