For SMBs that rely on rapid, scalable solutions to manage extensive datasets, Apache Hadoop is an indispensable tool. 

Before Hadoop, traditional databases were designed for single-server environments. With larger and larger amounts of data and memory requirements comes the need for multiple servers. Attempting to use a traditional database for a multi-server setup leads to certain challenges.

  • Maintaining data consistency
  • Managing transactions across multiple nodes
  • Querying data across servers without heavy customization or additional tools

Hadoop solves these issues. It’s also designed to run on commodity hardware (not specialized or high-end) that’s commonly provided by hosting services. However, it’s a good idea to ensure your hosting provider supports Hadoop-specific configurations and networking setups.

You can think of Hadoop as a powerful librarian that can quickly organize and find vast amounts of information, like transaction data or logs, for business purposes.

In this article, we’ll explore how the Hadoop big data framework manages large datasets and can be used to derive actionable business insights.

We’ll also provide more technical insight into its architecture, components, industry-specific use cases, and how comprehensive hosting solutions enhance Hadoop’s capabilities.

What is Hadoop?

Apache Hadoop is an open-source framework that stores and processes large data sets across clusters of computers. It uses simple programming models to manage data without requiring high-level technical skills to process data.

The tool distributes computing tasks across multiple machines to increase data processing and improve data accuracy while reducing the risk of data loss. If one server in a network goes down, Hadoop’s system reroutes or replicates the data and processing tasks to other machines in the cluster.

Hadoop helps businesses manage large amounts of data by breaking it down and storing it across multiple locations, making it easier and more affordable to handle big datasets. However, it didn’t start out that way.

The origin of Hadoop

Hadoop originated from a paper published by Google on the MapReduce system. The concepts outlined in the paper inspired Doug Cutting and Mike Cafarella to apply these principles to a framework.

They initially created Hadoop as a part of the Nutch project, which aimed to offer a free web search platform. This evolved into a sprawling, open-source framework designed to handle and process large volumes of data.

Comparison with traditional systems

Hadoop differs from traditional relational database management systems (RDBMS) in its ability to scale up to large volumes of data.

RDBMS typically handle structured data and are constrained by memory and storage capacity when scaling, leading to increased costs and complexity.

In contrast, Hadoop processes and stores both structured and unstructured data, like texts and images, across many low-cost computers. It’s this ability to handle large quantities and a variety of data (free of charge or licensing requirements) that makes Hadoop so advantageous. 

Core components of Hadoop

Hadoop is made up of several components that help to process and manage large sets of data. In the sections below, we go into more detail about how each component works.

Hadoop Distributed File System (HDFS)

HDFS works to store large amounts of data across multiple machines. It’s also built to handle failures, allowing continuous access to data even during hardware malfunctions.

Because HDFS distributes a high throughput of data processing tasks, it’s also ideal for applications that need to manage and analyze large data sets quickly. This includes healthcare providers, financial services, e-commerce platforms, retail chains, or any business that requires quick access to large volumes of information.

MapReduce

MapReduce processes substantial data sets efficiently across a network of computers. This approach is particularly beneficial for organizations that need to handle large volumes of data but may not have the resources of larger enterprises. Specifically, it works in two main phases: the map phase and the reduce phase.

Map

In this initial phase, the map function takes input data and converts it into another dataset. The output data is then broken down into individual elements (called tuples or key/value pairs). This process helps to organize a large, cluttered database into a well-indexed file system, making it quicker and easier to locate specific data points. 

For businesses, this means speedy data retrieval and processing, which is especially useful for those relying on analytics for timely decision-making.

Reduce

Following the mapping stage, the reduce function aggregates these tuples into a smaller set of tuples. This step consolidates the results into a comprehensive output that’s easier for businesses to analyze. 

For example, if the map function pairs each sale with its corresponding product, the reduce function might aggregate these results to produce the total sales per product.

Yet Another Resource Negotiator (YARN)

YARN’s main job is to allocate the computing resources available across a cluster of machines so that different data processing tasks are executed effectively. It enables more dynamic resource allocation compared to earlier Hadoop versions for greater scalability and better resource usage. 

YARN is particularly important for organizations that need a cost-effective and accessible big data solution that also optimizes processing time and resource use, such as CPU power, RAM, disk storage, and network bandwidth.

Additionally, YARN’s ability to schedule user jobs systematically helps with data processing tasks. It does this by assigning the necessary computing power, memory, and storage to each task as needed. 

YARN adjusts assignments on the fly, depending on what each task requires, such as more processing power for complex calculations or additional memory for large data sets. 

The resource manager keeps track of how each resource is used and prioritizes tasks to ensure everything runs smoothly across the cluster, preventing slowdowns.

Apache Hadoop Common

Apache Hadoop Common includes all the most important tools and software components needed for Hadoop to work properly. It allows the system to operate seamlessly by providing the necessary framework for the other Hadoop services (HDFS, MapReduce, and YARN). 

It also includes a suite of network and data input/output utilities that make data storage and processing possible across different hardware and network configurations. 

Apache Hadoop Common is an extensive library (that includes other libraries), but it also acts as a repository for developers to add, remove, or collaborate on the components. It includes a wide variety of utilities that support the core functions of the Hadoop ecosystem. Here’s a list of some of the more prominent utilities and libraries.

  • I/O libraries: Handles data serialization and deserialization and provides a common framework for the different data types used across Hadoop.
  • Configuration management: Manages the configuration of Hadoop systems, allowing for the customization and tuning of parameters.
  • Remote procedure call (RPC) system: Supports communication between different nodes in the Hadoop cluster, which is essential for distributed computing.
  • Serialization libraries: Facilitates efficient data exchange between computers in the cluster.
  • Native libraries: Enhances performance and integration with underlying host operating system capabilities.
  • Authentication, authorization, and security: Includes features for secure data processing, such as Kerberos authentication and user-level authorizations.
  • Logging and diagnostics: Provides logging utilities that help in debugging and monitoring the operations of Hadoop clusters.
  • HTTP and RPC servers: Utilized for network communication between Hadoop components and for client interactions.

Advantages of using Hadoop

The advantages of using Hadoop are scalability, cost-effectiveness, and efficiency. However, all of these really work towards Hadoop’s main advantage for businesses: scalability. The ability to scale to larger datasets and multi-server environments in a cost-effective and efficient way opens up opportunities for businesses to scale their operations in other ways.

Scalability

Hadoop grants scalability by supporting evolving data needs. It enables nodes to be added to its cluster without experiencing downtime or performance degradation. As data volume grows, businesses can simply increase their cluster size to handle up to petabytes of data efficiently.

For example, a digital marketing agency might start with a small cluster to analyze consumer behavior data and then scale up as their data accumulates or as client demands increase.

The scalable nature of Hadoop allows companies to maintain high performance and reliability regardless of data size, making it a great choice for businesses with big data management needs looking to mitigate the cost of high-end hardware.

Cost-effectiveness

Hadoop stands out for its cost-effectiveness, which comes from its lack of required licensing and compatibility with commodity hardware. 

By utilizing commodity hardware, which is much cheaper than proprietary hardware, Hadoop reduces the financial barrier to entry for managing massive volumes of data. Not only is the initial hardware cost lowered, but ongoing maintenance expenses are also decreased.

For small businesses and agencies, this means they are able to undertake large-scale data processing and storage projects that would normally be too expensive. Additionally, Hadoop’s affordability allows organizations to invest more in analytics, customer engagement, and other strategic areas.

Efficiency

Hadoop improves data processing by spreading tasks across many computers in its network, parallelizing, or working on them at the same time. Instead of one computer handling all tasks sequentially, several machines work on different parts of the task simultaneously, significantly reducing the time to process data.

This capability is especially valuable in environments where the speed of insights from data analytics provides a competitive edge.

Practical use cases of Hadoop

Now that we’ve thoroughly explored what Hadoop is and how it works, let’s look at some specific use case examples in a few different industries.

Healthcare data management

In healthcare, managing large datasets is crucial to patient care and operational efficiency.

By providing tools that store, process, and analyze vast amounts of data, Hadoop allows healthcare providers to quickly access and interpret complex data such as patient records and treatment outcomes.

Hadoop also helps healthcare organizations integrate disparate data sources, such as electronic health records, imaging data, and genomic data, into a cohesive system. This integration facilitates advanced analytics, like predictive modeling for patient outcomes or personalized medicine approaches, which rely on the quick processing of large datasets.

Furthermore, the insights gained from Hadoop-based analytics help healthcare providers make more informed decisions, improving treatment accuracy. These actionable insights lead to better resource management, reduced costs, and enhanced patient satisfaction.

Ecommerce customer behavior analysis

Understanding customer behavior is the guiding light of success in ecommerce. By knowing how customers interact with your online store — what they search for, how they navigate, and what drives their purchases — you can tailor your offerings, improve the user experience, and ultimately boost sales and customer satisfaction.

Hadoop’s big data processing capabilities make it a powerful tool for ecommerce businesses looking to analyze extensive customer interaction data and improve their marketing strategies. 

Businesses can use Hadoop to process large volumes of data generated from online transactions, website navigation, and customer feedback in real time.

Hadoop can also aggregate and analyze diverse data points to create detailed customer profiles and predict buying patterns. These deep insights lead to tailored, more effective marketing efforts in terms of optimizing promotions, pricing, and product recommendations.

For example, by analyzing clickstream data, businesses might identify certain products that are frequently browsed together and adjust cross-selling strategies accordingly.

Moreover, the actionable intelligence gleaned from Hadoop-driven analytics improves user experiences by delivering more personalized content and recommendations. This not only drives sales but also improves customer satisfaction and loyalty.
