Is it possible to run Java code on Zeppelin Notebook?
Hi All,
I am a new user of Zeppelin and got to know that Apache Zeppelin is using Spark as the backend interpreter.
Till date, I have run some codes written in Scala on the Zeppelin notebook. However, I am pretty familiar with writing Spark application using Java.
Now my question: is it possible to run Java code on Zeppelin Notebook?
Thanks and Regards,

Hi Alexander,
Thanks for replying me. I am particularly interested in running Spark code written in Java on Zeppelin Notebook.

Actually, there is a not very well known yet "hack" (I talked about it a bit on ApacheCon this year) - to run a pure Java paragraph in Apache Zeppelin - you can just use `%beam` interpreter!
Beam interpreter uses Beam Java API, so you can leverage it i.e to run WEKA machine learning library (pure Java) in Zeppelin as below
```%beam
import java.io.BufferedReader;import java.io.FileReader; import weka.classifiers.Classifier;import weka.classifiers.lazy.IBk;import weka.core.Instance;import weka.core.Instances;import weka.core.Instances;
public class KNN {
public static void main(String[] args) throws Exception { BufferedReader datafile = new BufferedReader(new FileReader("/home/ubuntu/ads-weka.txt")); Instances data = new Instances(datafile); data.setClassIndex(data.numAttributes() - 1); //do not use first and second Instance first = data.instance(2); Instance second = data.instance(3); data.delete(2); data.delete(3); Classifier ibk = new IBk(); ibk.buildClassifier(data); double class1 = ibk.classifyInstance(first); double class2 = ibk.classifyInstance(second); System.out.println("first: " + class1 + "\nsecond: " + class2); }}```
It will compile the code the classes and execute it.
You just need to remember to build Zeppelin with `-Pbeam` (may be can be added to the release convenience binary as well?)

Good question :)
Actually, there is a not very well known yet "hack" (I talked about it a
bit on ApacheCon this year) - to run a pure Java paragraph in Apache
Zeppelin - you can just use `%beam` interpreter!
Beam interpreter uses Beam Java API, so you can leverage it i.e to run WEKA
machine learning library (pure Java) in Zeppelin as below
```
%beam
import java.io.BufferedReader;
import java.io.FileReader;
import weka.classifiers.Classifier;
import weka.classifiers.lazy.IBk;
import weka.core.Instance;
import weka.core.Instances;
import weka.core.Instances;
public class KNN {
public static void main(String[] args) throws Exception {
BufferedReader datafile = new BufferedReader(new
FileReader("/home/ubuntu/ads-weka.txt"));
Instances data = new Instances(datafile);
data.setClassIndex(data.numAttributes() - 1);
//do not use first and second
Instance first = data.instance(2);
Instance second = data.instance(3);
data.delete(2);
data.delete(3);
Classifier ibk = new IBk();
ibk.buildClassifier(data);
double class1 = ibk.classifyInstance(first);
double class2 = ibk.classifyInstance(second);
System.out.println("first: " + class1 + "\nsecond: " + class2);
}
}
```
It will compile the code the classes and execute it.
You just need to remember to build Zeppelin with `-Pbeam` (may be can be
added to the release convenience binary as well?)

I think you will need to convert Java code into Scala syntax? But Scala can call into Java libraries and so on.
I don't think we have an interpreter for Java since it does not come with a REPL until Java 9?
