BigData and Hadoop are two widely recognized terms in the current landscape, and they are closely interconnected. The processing of Big Data often relies on the utilization of Hadoop.
This article aims to provide a concise overview of the distinctions between BigData and Hadoop by covering the key terms, features, and advantages of employing it.
Let’s dive in!
What is BigData?
Bigdata refers to the massive amount of data, information, or related statistics processed by large organizations and ventures.
Big Data includes 7 key “V” factors: Velocity, Variety, Volume, Value, Veracity, Visualization, and Variability. Due to the unique challenges posed by managing such data, the demand for individuals with specialized skills in this field is on the rise. Many people are aspiring to complete certification courses in Big Data to meet this growing demand.
Organizations develop various software applications and process tons of data daily. Thus it makes it difficult to process those big data manually. Big data helps to discover the pattern and make informed decisions related to interaction technology and human behavior.
Enrolling in a Big Data and Hadoop course is an excellent way to acquire the skills and knowledge needed to work with large datasets and master the Hadoop framework for efficient data processing.
How does Big Data work?
Big data analytics involves the collection, processing, cleaning, and analysis of large datasets to help organizations make practical use of their big data.
Collecting Data
Every organization has its way of gathering data. With today’s technology, data can be sourced from various places, including cloud storage, mobile apps, and in-store IoT sensors. Some data is stored in data warehouses for easy access, while more complex or diverse data goes into a data lake with assigned metadata.
Processing Data
Once collected, data needs to be organized for accurate analytical results, especially when dealing with large and unstructured datasets. The challenge grows as available data expands exponentially. Batch processing examines large data blocks over time, suitable for scenarios with a longer turnaround between data collection and analysis. On the other hand, stream processing looks at smaller data batches, reducing the delay for quicker decision-making, albeit at a potentially higher cost.
Cleaning Data
Regardless of size, data needs scrubbing for better quality and stronger results. Correct formatting and the elimination of duplicative or irrelevant data are essential. Dirty data can mislead, creating flawed insights.
Analyzing Data
Turning big data into usable insights is a gradual process. Once prepared, advanced analytics methods come into play:
- Data mining identifies patterns and relationships by sifting through large datasets, pinpointing anomalies, and forming data clusters.
- Predictive analytics uses historical data to predict future trends, and recognize upcoming risks and opportunities.
- Deep learning, mimicking human learning patterns, employs artificial intelligence and machine learning to uncover patterns in complex and abstract data through layered algorithms.

What is Hadoop?
Hadoop is open-source software and comprises of cluster of machines to handle the massive amount of data. It also comes up with distributed storage and distributed processing to handle huge amounts of data.
This can be possible with the usage of the MapReduce programming model.
Hadoop can be easily implemented in the Java tool and it can do data mining in any data form such as structured, unstructured, or semi-structured. Moreover, it is highly scalable.
Hadoop architecture consists of three major components such as:
- HDFS: It refers to a reliable storage system with major data stored in it.
- MapReduce: This layer consists of a distributed processor.
- Yarn: This layer is composed of the resource manager
One of the driving forces behind the significant growth of Hadoop technology is that it has distinct features. Unlike other frameworks, Hadoop can partition consumer jobs into various separate subtasks. It can permit code translation into information and this significantly reduces the network traffic.
How does Hadoop work?
Hadoop simplifies the utilization of storage and processing capacity across cluster servers, enabling the execution of distributed processes on massive datasets. It serves as the foundational framework upon which other services and applications can be constructed.
For applications collecting data in diverse formats, integration with the Hadoop cluster involves utilizing an API operation to connect to the NameNode. The NameNode manages the file directory structure and the distribution of “chunks” for each file, which are replicated across DataNodes.
Running a data query job involves providing a MapReduce job composed of numerous map and reduce tasks that operate on the data stored in the Hadoop Distributed File System (HDFS) across the DataNodes. Map tasks execute on each node, processing input files, while reducers aggregate and organize the final output.
Exploring a Big Data and Hadoop tutorial can be a helpful starting point for individuals looking to grasp the fundamentals of managing and analyzing large datasets using the Hadoop ecosystem.
Big Data and Hadoop Differences
Big Data and Hadoop are often used together, but they refer to distinct concepts in the field of data processing. Here is the tabulated BigData and Hadoop differences:
| Aspect | Big Data | Apache Hadoop |
| Definition | Big Data is a group of technologies. It is a collection of huge data that continuously multiplies. | Apache Hadoop is an open-source Java-based framework that incorporates some of the principles of big data. |
| Complexity | It is a collection of assets that are quite complex, complicated, and ambiguous. | It achieves a set of goals and objectives for dealing with the collection of assets. |
| Problem | It represents a complicated problem involving a huge amount of raw data. | It serves as a solution for processing large volumes of data. |
| Accessibility | Big Data is harder to access. | Apache Hadoop allows data to be accessed and processed faster. |
