Comparison of Apache Spark and Apache Hadoop
What is Spark?
Apache Spark is an open-source, distributed computing framework designed for large-scale data processing and analytics. It was created by the Apache Software Foundation and first released in 2014. Spark provides an efficient and flexible platform for processing big data, with support for various programming languages such as Scala, Python, and Java. Spark is built around the concept of a Resilient Distributed Dataset (RDD), which allows for distributed data processing and caching. It offers high-speed processing capabilities, with support for in-memory computing and parallel processing. Spark has a wide range of applications, including data processing, machine learning, graph processing, and more.
What is Hadoop?
Hadoop is an open-source framework designed for distributed storage and processing of large-scale data sets. It was created by the Apache Software Foundation and first released in 2011. Hadoop is built on the concept of a distributed file system called Hadoop Distributed File System (HDFS), which allows data to be stored across multiple machines in a cluster. It also provides a MapReduce programming model for processing and analyzing large data sets. Hadoop has a highly scalable architecture, making it suitable for handling big data in a cost-effective manner. It is widely used in various applications, including data processing, machine learning, and data warehousing.
