Big Data and Hadoop: Revolutionizing Data Processing and Analytics

Want to learn the connection between Hadoop and big data? This comprehensive Hadoop tutorial guide narrates the ecosystem, scalability, and real-world applications of Hadoop. Dive into the post to learn how Hadoop is advancing data processing and analytics.

Definition and Characteristics of Big Data

Big data contains greater variety and arrives in increasing volumes with more velocity. It can be unstructured, structured, and semi-structured (and can be collected from different sources). Big data comprises the following five characteristics:

  • Velocity
  • Volume
  • Value
  • Variety
  • Veracity

Challenges and Opportunities Posed by Big Data

Big data offers these benefits:

  • Inexpensive
  • Offers market insights
  • Product development opportunities

Big data poses the following challenges:

  • Maintenance of data quality is difficult
  • Data security issues

 

What is Hadoop in Big Data?

If you want to know what is hadoop in big data, learn its definition first. Hadoop is a Java-based framework. It was developed by Michael J. Cafarella and Doug Cutting. Hadoop uses the MapReduce programming model for speedier retrieval and storage of data from the nodes. 

Introduction to Hadoop Framework and its Components

So, what is Hadoop in big data? This open-source framework stores and processes big data. The data gets stored on the commodity servers running as clusters. The distributed file system allows for concurrent processing as well as fault tolerance. The three components of Hadoop are mentioned below:

  • Hadoop HDFS: The storage unit which manages and monitors the distributed file system
  • Hadoop MapReduce: The processing unit which manages processing requests
  • Hadoop YARN: The resource management unit which works on two functionsMap() and Reduce()

Role of Hadoop in Handling and Processing Big Data

Hadoop can store and process data across the cluster of commodity hardware. After the client submits data & program to the cluster, HDFS stores the data. On the other hand, MapReduce processes the stored data, while YARN divides the work and assigns the resources.

Note down the major differences between data science and artificial intelligence here.

Distributed Computing and Scalability in Hadoop

Unlike conventional systems, big data Hadoop does not limit data storage. It is scalable because it can operate in a distributed environment. Its setup can also be expanded to add more servers storing more petabytes of data.

Hadoop Ecosystem

Hadoop is a platform that comprises different integral components allowing distributed data processing and storage. There are some supplementary components used in this ecosystem:

  • Hive: The data warehousing system assists in querying datasets in Hadoop HDFS
  • Pig: Similar to Hive, it can eliminate the need for MapReduce functions. 
  • Flume: It gathers, aggregates, and sends streaming data (acts as the courier service between HDFS and datasets)
  • Sqoop: Similar to Flume, but used for exporting data to and from & importing data into relatable databases
  • Zookeeper: This service coordinates distributed applications and acts as the admin tool having a centralized registry with key information about distributed servers that it handles
  • Kafka: This distributed publish-subscribe messaging platform is used with Hadoop for speedier data transfers

Data Storage and Processing with Hadoop

Hadoop HDFS is the storage unit that manages and monitors the distributed file system. MapReduce is the processing unit that manages all processing requests. These two components in Hadoop are important for storing and processing data.

Handling Structured and Unstructured Data in Hadoop

Hadoop handles structured and unstructured data. It processes unstructured data contested and deployed for managing the structured data. MapReduce writes applications processing structured & unstructured data in the system. On the other hand, YARN divides the tasks, thereby assigning the resources.

Big Data Analytics with Hadoop

With several applications generating big data, Hadoop plays an integral role in offering the required transformation that the database world needs. For big data analytics, data is gathered in Hadoop about people, objects, processes, and tools. Hadoop can overcome the challenges of big data’s vastness

Real-world Use Cases of Hadoop

Given below are some real-world cases of big data Hadoop:

  • Retail analytics for any inventory forecasting
  • Retail analytics for dynamic product pricing
  • Supply chain efficacy
  • Retail analytics for customized and targeted marketing as well as promotion

Hadoop and Data Security

Hadoop HDFS implements transparent encryption. After it is configured, data is encrypted and decrypted without changes to the application code. Kerberos is a safe and seamless network authentication protocol that Hadoop uses for network and data security.

Limitations and Challenges of Hadoop

Given below are some challenges and limitations of Hadoop:

  • Cannot handle small files
  • Processing speed is slow
  • Has Batch Processing support only
  • Real-time Data Processing is not available
  • Not efficient for interactive processing since Hadoop doesn’t support cyclic data flow

Future of Hadoop and Big Data

The emerging advancements of big data Hadoop are AWS CDK project work for a real-time IoT infrastructure, multi-source data processing, and more. As per the reports, the Hadoop and big data industry is expected to boom flourishingly.

Conclusion

So, this post has clearly narrated what is Hadoop and how it is revolutionizing data processing and analytics. Basically, Hadoop is an open-source distributed computing framework that enables the processing of large-scale data sets across clusters of commodity hardware. It consists of the Hadoop Distributed File System (HDFS) for data storage and the MapReduce programming model for data processing, allowing for scalable and reliable data processing in big data applications.
