Unless java is setup and validated successfully do not go further.

WinUtils is required for HDFS APIs to work on Windows laptop.

Once applications are developed using IDE, they are typically built using tools like sbt Tools like git facilitate team development.

IDEs are typically integrated with other tools such as git which is code versioning tool.

Typically programming will be done with IDEs such as IntelliJ.

For integrated development using IntelliJ.

We will start with Java/JDK on Windows laptop and we will go through step by step instructions to setup Scala, sbt, WinUtils etc.

We will also develop few programs to validate whether our setup is progressing as expected or not.

How we can validate whether it is working as expected?.

Setup development environment on Windows.

Here is a full example of a standalone application to test PySpark locallyĬount = sc.parallelize(range(0, NUM_SAMPLES)) \

Sc = pyspark.SparkContext(appName="myAppName") To install findspark just type: $ pip3 install findsparkĪnd then on your IDE (I use Eclipse and Pydev) to initialize PySpark, just call: You can address this by adding PySpark to sys.path at runtime. Sometimes you need a full IDE to create more complex code, and PySpark isn’t on sys.path by default, but that doesn’t mean it can’t be used as a regular library. The result: Running PySpark in your favorite IDE To check if your notebook is initialized with SparkContext, you could try the following codes in your notebook:ĭots = sc.parallelize().cache() The PySpark context can be sc = SparkContext.getOrCreate() Create a new notebook by clicking on ‘New’ > ‘Notebooks Python ’. This command should start a Jupyter Notebook in your web browser. Restart (our just source) your terminal and launch PySpark: $ pyspark Your ~/.bash_profile file may look like this: Just add these lines to your ~/.bash_profile file: export PYSPARK_DRIVER_PYTHON=jupyterĮxport PYSPARK_DRIVER_PYTHON_OPTS='notebook'

Now to run PySpark in Jupyter you’ll need to update the PySpark driver environment variables. # For python 3, You have to add the line below or you will get an error To do so, edit your bash file: $ nano ~/.bash_profileĬonfigure your $PATH variables by adding the following lines to your ~/.bash_profile file: export SPARK_HOME=/opt/spark To find what shell you are using, type: $ echo $SHELL Lrwxr-xr-x 1 root wheel 16 Dec 26 15:08 /opt/spark̀ -> /opt/spark-2.4.0įinally, tell your bash where to find Spark. The contents of a symbolic link are the address of the actual file or folder that is being linked to.Ĭreate a symbolic link (this will let you have multiple spark versions): $ sudo ln -s /opt/spark-2.4.0 /opt/spark̀Ĭheck that the link was indeed created $ ls -l /opt/spark̀ $ sudo mv spark-2.4.0-bin-hadoop2.7 /opt/spark-2.4.0Ī symbolic link is like a shortcut from one file to another. Unzip it and move it to your /opt folder: $ tar -xzf spark-2.4.0-bin-hadoop2.7.tgz Select the latest Spark release, a prebuilt package for Hadoop, and download it directly. Make sure you have Java 8 or higher installed on your computer and visit the Spark download page Install Jupyter notebook $ pip3 install jupyter Install PySpark
