Hadoop

Definition

Hadoop is an open-source software framework that enables 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, thereby enabling highly scalable and fault-tolerant data processing and analysis.

5 Must Know Facts For Your Next Test

1. Hadoop enables the processing and analysis of large, complex datasets that traditional database systems struggle with, making it particularly useful for big data applications.
2. The Hadoop ecosystem includes several related projects and technologies, such as HDFS, MapReduce, Hive, Pig, Spark, and Kafka, which work together to provide a comprehensive data processing and analytics platform.
3. Hadoop's distributed architecture allows it to scale out by adding more nodes to a cluster, providing increased processing power and storage capacity as needed.
4. Hadoop's fault-tolerance and data replication features make it resilient to hardware failures, ensuring that data and computations are not lost even when individual nodes fail.
5. Professionals with a joint education in accounting and information systems can leverage Hadoop and the broader big data ecosystem to enhance data-driven decision-making, improve financial reporting and analysis, and uncover valuable insights from large, unstructured datasets.
