Hadoop is an open source, Java-based programming framework that supports the processing and storage of large data sets in a distributed computing environment. It can quite easily expand from single servers to thousands of machines, each providing computation and storage.
Apache Spark is a fast, in-memory data processing engine with elegant and expressive development APIs. Spark can efficiently execute streaming, machine learning or SQL workloads that require fast iterative access to datasets. Data Scientists commonly use machine learning to decipher large and complex unorganized data and Spark can help them in their need for iterative data processing.
