Reading several answers on Stack Overflow and the official documentation, I came across this:
#HOW TO LEARN SQL ON MAC INSTALL#
Please note that with Spark 2.2 a lot of people recommend just to simply do pip install pyspark .I try using pip to install pyspark but I couldn’t get the pysparkcluster to get started properly. ** Node is single entity machine or server.

One particularly challenging area is data processing. However, when you have huge dataset(in tera bytes or giga bytes), there are some things that your computer is not powerful enough to perform. This machine works perfectly well for applying machine learning on small dataset. Typically when you think of a computer you think about one machine sitting on your desk at home or at work. Internet powerhouses such as Netflix, Yahoo, and eBay have deployed Spark at massive scale, collectively processing multiple petabytes of data on clusters of over 8,000 nodes. This presents new concepts like nodes, lazy evaluation, and the transformation-action (or ‘map and reduce’) paradigm of programming.In fact, Spark is versatile enough to work with other file systems than Hadoop - like Amazon S3 or Databricks (DBFS). So, Spark is not a new programming language that you have to learn but a framework working on top of HDFS. This allows Python programmers to interface with the Spark framework - letting you manipulate data at scale and work with objects over a distributed file system. Spark is implemented on Hadoop/HDFS and written mostly in Scala, a functional programming language.However, for most beginners, Scala is not a great first language to learn when venturing into the world of data science.įortunately, Spark provides a wonderful Python API called PySpark.
