So to use PySpark, let’s install PySpark on Mac. Py4J is a Java library that is integrated within PySpark and allows python to dynamically interface with JVM objects, hence to run PySpark you also need Java to be installed along with Python, and Apache Spark. Spark was basically written in Scala and later on due to its industry adaptation its API PySpark was released for Python using Py4J. PySpark is a Spark library written in Python to run Python applications using Apache Spark capabilities. If you already have Python 2.7 or the latest then ignore this step. Since Spark is written in Scala language it is obvious you would need Scala to run Spark programs however to run PySpark this is optional.Īs you would know, PySpark is used to run Spark jobs in Python hence you also need Python to install on Mac OS.
Run the below command in the terminal to install it.īrew install 3. Since Oracle Java is not open source anymore, I am using the OpenJDK version 11.
