By streamlining the creation, organization, and processing of software across various Hadoop modules, Hadoop Common aims to enable seamless communication and data transfer between the nodes of a Hadoop cluster, thereby contributing to the efficient operation of Hadoop in its entirety. In order to fulfill its function of fostering communication and enhancing the performance of Hadoop, Hadoop Common is used for a range of practical purposes.
For instance, developers working with data-intensive applications often employ Hadoop Common to manage their software utilities, as the component provides support for critical processes involving source code compilation, serialization, and deserialization. Moreover, the module’s native libraries contribute to the prompt execution of tasks, helping users to exploit comprehensive records from large datasets.
Ultimately, Hadoop Common plays a foundational role in the innovative data processing capabilities of the Hadoop framework, enabling users to capitalize on the immense potential of big data analytics.
Examples of Hadoop Common
Hadoop Common, also known as Apache Hadoop, is a widely-used open-source framework designed for distributed storage and processing of large data sets. Here are three real-world examples of organizations and industries utilizing Hadoop Common to address their big data needs:
Healthcare: Numerous healthcare organizations and research institutions use Hadoop for processing, storing, and analyzing the vast amounts of data generated from medical records, clinical trials, and genomic studies. An example is the National Cancer Institute, which leverages the Hadoop framework to analyze genomic data for cancer research, helping researchers better understand genetic mutations and develop personalized treatment plans.
Telecommunications: Telecommunications companies collect and process vast amounts of customer data, including call records, user profiles, social media interactions, and more. Companies like Verizon use Hadoop Common to derive insights, predict customer churn, and identify network issues simultaneously. By processing and analyzing this data in real-time, telecom providers can offer better customer service, targeted marketing campaigns, and optimized network performance.
Finance and Banking: Financial institutions such as banks and credit card companies generate and handle massive amounts of data, including customer transactions, purchasing patterns, and credit scores. These organizations utilize Hadoop Common to process and analyze the data to detect and prevent fraud, assess credit risks, and provide customized financial services to clients. For instance, Mastercard uses Hadoop technologies to analyze billions of transactions and improve fraud detection while providing personalized offers to its customers.
