10 years back, there was lack of knowledge & unawareness of technologies required to store and process Big Data. Hence, organisations developed various Big Data related technologies to store and analyse Big Data, and Hadoop is one of the pioneer technologies. To know how Data evolved as Big Data & how Hadoop emerged as the solution to the problems related to Big data, go through this What is Hadoop blog. Rise of new technologies lead to new career options as well. In this Hadoop career blog, I will guide you through the career path in Hadoop and other Big Data technologies.
Organisations have now realized the benefits of Big Data analytics. It helped them in getting better business insights, which enhanced their decision-making capabilities. As organisations are showing interest in Big Data and are adopting Hadoop to analyse it. Hence, the demand of jobs in Big Data and Hadoop is also rising rapidly. If someone is interested in analyzing data and wants to pursue his or her career in this field, for them now is the right time to start learning Hadoop and Spark. This would always give you a good start either as a fresher or experienced. There is a huge demand for professionals who can work on Big Data. Let me tell you about some predictions:
I would like you to go through this blog -> Why Big Data analytics is the best career move. Let us move on and understand the skills that might give you a head start in your upcoming Hadoop career.
I know the next thing which comes to your mind is about the skills required to learn Big Data & Hadoop. I would like to tell you that there is no such pre-requisite in learning Hadoop. But of course, Linux knowledge will give you head start while working with Hadoop. If you are from programming background and you know Java, Scala or Python, it would be easier for you to learn how to write a MapReduce program in different programming languages and execute parallel processing over HDFS (Hadoop storage). If you know SQL, you will get a head start in learning Hadoop ecosystem tools like Pig, Hive etc. Similarly, if you have worked with NoSQL databases you will feel comfortable in working with HBase. I would recommend you to go through this Hadoop Ecosystem blog to know various tools that are present in the Hadoop Ecosystem.

Figure: Hadoop Career- Different Big Data Domains
It gives you early warning for securities fraud & trade visibility in Banking & Finance Sector. It helps in card fraud detection, audit trails & enterprise credit risk reporting. Customer data are transformed and analyzed for better insights & efficient decision making capabilities.
The SEC (U.S. Securities and Exchange Commission) is using Big Data to monitor financial market activity by using network analytics and Natural Language Processors. This helps to catch illegal trading activity in the financial markets.
In this domain, consumer data is collected, analyzed and utilized to make better predictions and recommendations to the customers. It leverages mobile and social media content. For an example, Wimbledon Championships leverages big data to deliver detailed sentiment analysis on the tennis matches to users in real-time.
The rising medical costs, unavailability of data and unusable data like patient history and disease case histories are archived and not analyzed due to unstructured format. You can analyze the healthcare data and treat your patients accordingly based on previous case histories. You can also identify the disease that is common in a particular areas, so prevention can be taken and medicines can be made available to those areas.
The University of Florida used free public health data & Google Maps to create visual data that allows faster identification and efficient analysis of healthcare information.
In education sector, we are trying to incorporate data from varied sources and then utilize that data for improving education sector. University of Tasmania with over 26000 students has deployed a Learning and Management System that tracks log time, time spent on different pages and the overall progress of a student over time.
There are lot of government schemes which are in execution and are generating data at a tremendous speed. Integration and inter-operability of Big data from different Government schemes will improve the efficiency of the schemes and will provide better outcomes.
The Food and Drug Administration(FDA) is using Big Data to detect and study patterns of food-related illness and diseases, allowing for faster treatment responses.
Data from location-based social networks and high speed data from telecoms have effected travel behavior. Transport demand models are based on new social media structures. Big Data Analytics in transportation will improve Traffic control, Route planning, Congestion Management system, Revenue Management, Technological Enhancements, etc.
60% of electricity grid assets will need replacement in this decade. Smart meters become main-stream, as consumers want more control & insights into energy consumption. Smart meter readers allow data to be collected in almost every 15 minutes. This data is used to analyze consumption of utilities better.
We have just discussed about some of the domains where Big Data analytics can do wonders. In each and every domain Big Data can be analyzed giving better insights.
I hope this blog was informative and added value to you. There is a huge scope of building a successful Hadoop career in almost every domain like Healthcare, Banking, Telecom, Social Media, Retail etc.
