#Data Science in 30 Minutes: Spark Streaming and Basic Analysis

You can easily install all of the Python requirements with Continuum Analytics' conda - if you haven't heard of it yet, we'd highly recommend taking a look!
The easiest way to install all these packages is the following, once you've gotten conda installed:
conda env create --name ds30 --file environment.yml
More importantly you'll need a working PySpark install (have pyspark in your path). You can download Spark here.
The presentation uses Jupyter notebooks, with a Scala/Spark kernel for ingesting data and a Python kernel for analysis.
The following will help you duplicate our (admittedly aged) kernel setup. We'll assume that you have already installed a Python environment, iPython, and Jupyter through either Anaconda or some other method.
- You will need to have a working Java installation with $JAVA_HOME set. On Ubuntu, you can e.g.
sudo apt-get install default-jdk. wget https://oss.sonatype.org/content/repositories/snapshots/sh/jove/jove-spark-cli_1.3_2.10/0.1.1-1-SNAPSHOT/jove-spark-cli_1.3_2.10-0.1.1-1-SNAPSHOT.tar.gz- Unpack with
tar xvf jove-spark-cli....tar.gz mv jove-spark-cli...SNAPSHOT jove-sparkfor convenience- Run
./jove-spark/bin/jove-spark-1.3 --kernel-spec - Check your installed kernels with
jupyter kernelspec list. You should see the Spark kernel installed.
If you choose to use a different (newer) kernel, the setup may vary. The three dependencies you'll need in the Scala/Spark kernel are:
- org.apache.spark %% spark-streaming % 1.3.1
- org.apache.spark %% spark-streaming-twitter % 1.3.1
- com.google.code.gson % gson % 2.4
Lastly, for Twitter data, you'll need to register an application and enter your credentials in the twitter4j.properties file.
This talk was created by Ariel M'ndange-Pfupfu, a Data Scientist at The Data Incubator. He has worked on a variety of data science, software engineering, and curriculum development projects and is also a current Bleeker Fellow. He earned his Master’s degree at Stanford and his Ph.D. in Materials Science & Engineering from Northwestern.
DataBricks, one of the largest contributors to the Apache Spark project, has been instrumental in developing and supporting Spark education. The reference applications book was very useful for building this talk.
