Contrasting Hadoop & Apache Cassandra â¢ Apache Cassandra is a NoSQL database ideal for high-speed, online transactional data, while Hadoop is a big data analytics system that focuses on data warehousing and data lake use cases.
Apache Hadoop is an open-source software framework written in Java for distributed storage and distributed processing of very large data sets on computer clusters built from commodity hardware.he list includes the HBase database, the Apache Mahout machine learning system, and the Apache Hive Data Warehouse system. Hadoop can in theory be used for any sort of work that is batch-oriented rather than real-time, is very data-intensive, and benefits from parallel processing of data.
