Hadoop vs Spark Framework: What are the differences?
Hadoop: Open-source software for reliable, scalable, distributed computing. The Apache Hadoop software library is a framework that allows for the distributed processing of large data sets across clusters of computers using simple programming models. It is designed to scale up from single servers to thousands of machines, each offering local computation and storage; Spark Framework: A micro framework for creating web applications in Kotlin and Java 8 with minimal effort. It is a simple and expressive Java/Kotlin web framework DSL built for rapid development. Its intention is to provide an alternative for Kotlin/Java developers that want to develop their web applications as expressive as possible and with minimal boilerplate.
Hadoop belongs to "Databases" category of the tech stack, while Spark Framework can be primarily classified under "Microframeworks (Backend)".
Hadoop is an open source tool with 9.4K GitHub stars and 5.85K GitHub forks. Here's a link to Hadoop's open source repository on GitHub.
Airbnb, Uber Technologies, and Netflix are some of the popular companies that use Hadoop, whereas Spark Framework is used by Kasa Smart, AfricanStockPhoto, and Khartec ltd. Hadoop has a broader approval, being mentioned in 309 company stacks & 623 developers stacks; compared to Spark Framework, which is listed in 5 company stacks and 4 developer stacks.

The MapReduce workflow starts to process experiment data nightly when data of the previous day is copied over from Kafka. At this time, all the raw log requests are transformed into meaningful experiment results and in-depth analysis. To populate experiment data for the dashboard, we have around 50 jobs running to do all the calculations and transforms of data.
in 2009 we open sourced mrjob, which allows any engineer to write a MapReduce job without contending for resources. We’re only limited by the amount of machines in an Amazon data center (which is an issue we’ve rarely encountered).
