Hadoop Developer Salary in India in 2024 [For Freshers & Experienced]

 Doug Cutting and Mike Cafarella created Hadoop way back in 2002. Hadoop originated from the Apache Nutch (an open-source web search engine) project, which was further a part of the Apache Lucene project. The goal was to design an open-source framework that allowed for data storing and processing in a distributed and automated computing environment.

Hadoop is a software framework explicitly created for Big Data management, storage, and processing. It not only stores massive volumes of data, but it can also run applications on multiple clusters of commodity hardware. 

Hadoop boasts of a highly scalable architecture, such that it can expand from a single server to hundreds and thousands of machines wherein each machine provides computation and storage. Its distributed feature enables speedy and seamless data transfer among the nodes in the cluster, thereby facilitating continued functioning even if a node fails. 

Thanks to Hadoop’s distributed architecture, high scalability, high fault tolerance, enormous processing power, and fast processing speed, it is the perfect data management tool for businesses of all sizes. As a result, not only large corporations but also small and medium-sized businesses are adopting Hadoop. This growing adoption and demand for Hadoop services are creating a huge need for skilled Hadoop experts in the industry. Hadoop Developer is one of the many coveted Hadoop roles in demand right now.

Who is a Hadoop Developer?

A Hadoop Developer specializes in handling and managing the requirements and processes associated with the Big Data domain. The job role is pretty similar to that of a Software Developer, with the only difference being that a Hadoop Developer focuses on Big Data.

Hence, Hadoop Developers must possess in-depth knowledge of Hadoop tools and concepts, be familiar with all the elements of the Hadoop ecosystem (HDFS, YARN, and MapReduce), and understand the individual functioning of those elements as well as how they work together within the Hadoop ecosystem. Hadoop Developers are primarily responsible for designing, developing, implementing, and managing Big Data applications.

The job of Hadoop Developers primarily revolves around Big Data. They collect data from disparate sources, clean and transform it, decode it to extract meaningful patterns, analyze it, and store it in a database for future use. They also prepare detailed visualization reports for the cleaned and transformed data using various Business Intelligence (BI) tools to help other stakeholders (particularly non-technical members) in the project understand the connotations of the extracted data.

Responsibilities of a Hadoop Developer

• To install, configure, and maintain the enterprise Hadoop environment.
• To source and collect data from multiple platforms in large volumes.
• To load data from different datasets and determine which is the best file format for a specific task. 
• To clean data to best fit the business requirements at hand using streaming APIs or user-defined functions.
• To build distributed, reliable, and scalable data pipelines for data ingestion and processing in real-time.
• To create and implement column family schemas of Hive and HBase within HDFS.
• To use different HDFS formats like Parquet, Avro, etc. to speed up system analytics.
• To understand the requirements of input to output transformations.
• To fine-tune Hadoop applications for improving their performance.
• To define Hadoop job flows.
• To review and manage Hadoop log files.
• To create Hive tables and assign schemas.
• To manage and deploy HBase clusters.
• To build new Hadoop clusters as and when needed.
• To troubleshoot and debug run time issues in the Hadoop ecosystem.

Benefits of learning Hadoop

1) Data safety:

Hadoop’s excellent fault tolerance ability makes it a suitable choice for large-scale companies looking to protect their data. It provides high-level protection for single and multiple data failures. Hadoop’s internal working implies that the data is conveyed to individual nodes wherein the data replicates to other nodes. You can expect a high Hadoop admin salary in India if you are proficient at ensuring the organization’s data safety.

2) Affordability:

The business’ datasets tend to increase with time. Hadoop offers an effective solution for the proper storage of voluminous data. The use of conventional RDBMS proves to be expensive for organizations to scale up their data. Thus, Hadoop offers an affordable solution for data scalability. When using those conventional systems, organizations occasionally have to restrict their data, but this issue is not found when using Hadoop.

It can store approx. hundreds of pounds for every Terabyte. So, it is useful as an authentic data storage solution for the voluminous data intended for future use. A decent big data Hadoop salary is guaranteed if the developers can proficiently explore all the benefits of Hadoop.

3) Scalability:

Implied from the name itself, it indicates the capability to manage massive data for growth purposes. Hadoop is one of the greatest scalable platforms when it comes to data storage. This is because it has the potential to disburse massive datasets among various parallel servers.

The conventional RDBMSs can’t scale huge volumes of data. Conversely, Hadoop can work on a myriad of nodes. The Hadoop admin salary in India is inclusive of how skilfully the developers can scale the data.

4) Quick operation:

The data present on the Hadoop system is allocated on a file system within a cluster called ‘Maps’. One of the unique features of Hadoop is the distributed file system. Hadoop facilitates the quick processing of data via the same servers that process the data. Moreover, it can process unstructured data at a speed of a few terabytes within a few minutes.

5) Versatility:

Hadoop supports structured as well as unstructured data. So, it facilitated the organizations to provide hassle-free access to different data sources. This is possible by simply switching among different data types. You can use Hadoop to deliver valued business insights from varied sources such as social media platforms, emails, clickstream data, etc.

Hadoop is also useful in log processing, data warehousing, market campaign investigation, fraud detection, and recommendation systems. So, the versatility of Hadoop suggests the outstanding Hadoop admin salary in India for skilled candidates.

6) Wide range of applications:

Hadoop provides topmost priority to data, and so it deters data loss. It makes the most of the data. Its architecture involves creating comprehensive sets of data rather than developing data samples for analysis. The comprehensive datasets lead to in-depth data analysis and provide optimal solutions. One of the reasons why many companies are happy to offer high big data Hadoop salary is that the developers can work on various types of applications.

7) Outstanding career opportunities:

Considering the huge share of organizations actively working with big data, Hadoop will have a considerable share in job opportunities in the future. The developers must have exceptional skills for data harnessing. So, Hadoop looks after framing cost-effective plans. In such cases, there will be more chances of obtaining a handsome big data Hadoop salary.
