Welcome to the Pyspark tutorial section.
The courses comprises of 4 folders containing notebooks. Folders and notebooks are sorted in order of difficulty given their name, so you should follow the numerotation. For example, you should finish all notebooks in 1-beginner before starting 2-novice. Likewise, when doing 2-novice finish the 1-... notebook before doing 2-....
Inside each notebook, we have documented a number of questions and unimplemented code cells answering the question, followed by a code cell which acts as test cases for the function called Graded cell. Your submission will be graded on how many test cases you pass given your implementation of the previous function. Be careful as the instructor has hidden test cases on his side so don't try to circumvent the system by just returning the expected value, and learn nothing.
- Anaconda 2019+
- Java 8. You may experience difficulties with Java 9. You can set the
JAVA_HOMEenvironment variable to point to the Java folder you want to use for the project. You may also install Java JDK 8 inside your Anaconda environment withconda install -c cyclus java-jdk.
We provide you with a requirements.txt which is used to download dependencies in a conda environment we will name pyspark-tutorial.
Go to Environments tab then tap Import button. Name it pyspark-tutorial. In the dropdown type of file select Pip requirement file .txt and browse to the requirements.txt file and press enter to create the environment. You should now be able to select the environment.
Go to Environments tab, select the pyspark-tutorial environment. When your mouse is over the environment, you should see a green arrow, click on it and select Open with Jupyter notebook. Then browse to the folder with all the notebooks.
conda create -n pyspark-tutorial python=3.6
conda activate pyspark-tutorial
pip install -r requirements.txt
jupyter notebook
Run a Jupyter Notebook session : jupyter notebook from the root of your project, when in your pyspark-tutorial conda environment.
When you are done with the environment, don't forget to deactivate your Anaconda environment : conda deactivate
At the end of the course, send your assignments by email to the instructor.
This repo is generated from a private nbgrader project with the solutions to the problems, which I use to autograde the students solutions.
You may create a pull request with the change in the notebook so I copy-paste it in the private repo and overwrite the files. It is normal if I close and don't merge your PR while overwriting the file with your change. Hopefully I find a better way to regenerate the release folder.
