By undertaking a course in Hadoop, a professional would be guaranteed of huge success. Following are the advantages that a professional would gain while taking a class in Hadoop-
• If a professional takes a course in Hadoop, then he or she will acquire the ability to store and process a massive amount of data quickly. This can be attributed to the fact that the load of data is increasing day by day with the introduction of social media and Internet of Things. Nowadays, businesses take ongoing feedback from these sites. Hence, a lot of data is generated in this process. If a professional undertakes a course in Hadoop, then he or she would learn how to manage this huge amount of data. In this way, he or she can become an asset for the company.
• Hadoop increases the computing power of a person. When an individual undertakes training in Hadoop, he or she would learn that Hadoop's computing model; is quite adept at quickly processing big data. Hence, the more computing nodes an individual uses, the more processing power they would have.
• Hadoop is important in the context of increasing the flexibility of a company’s data framework. Hence, if an individual pursues a course in Hadoop, they can significantly contribute to the growth of a company. When compared to traditional databases, by using Hadoop you do not have to preprocess data before storing. Hadoop facilitates you to store as much data as you want.
• Hadoop also increases the scalability of a company. If a company has a team of workers who are adept at handling Hadoop, then the company can look forward to adding more data by just adding the nodes. In this case, little supervision is needed. Hence, the company can get rid of the option of an administrator.
