Most users with a Python background take this workflow for granted. However, unlike most Python libraries, starting with PySpark is not as straightforward as pip install and import. It will be much easier to start working with real-life large clusters if you have internalized these concepts beforehand. You can also easily interface with SparkSQL and MLlib for database manipulation and machine learning. You distribute (and replicate) your large dataset in small, fixed chunks over many nodes, then bring the compute engine close to them to make the whole operation parallelized, fault-tolerant, and scalable.īy working with PySpark and Jupyter Notebook, you can learn all these concepts without spending anything. Spark is also versatile enough to work with filesystems other than Hadoop, such as Amazon S3 or Databricks (DBFS).īut the idea is always the same. This presents new concepts like nodes, lazy evaluation, and the transformation-action (or "map and reduce") paradigm of programming. Remember, Spark is not a new programming language you have to learn it is a framework working on top of HDFS. You could also run one on Amazon EC2 if you want more storage and memory. However, if you are proficient in Python/Jupyter and machine learning tasks, it makes perfect sense to start by spinning up a single cluster on your local machine.

These options cost money-even to start learning (for example, Amazon EMR is not included in the one-year Free Tier program, unlike EC2 or S3 instances).
Databricks cluster (paid version the free community version is rather limited in storage and clustering options).
