Big data is one of the topics that I find very interesting and is in strong demand in IT industry. Big data is nothing but a colossal amount of data generated by machines. First, the employees used to generate data and put it into computer systems. A few years later things evolved to the internet and users started generating their own data by signing up on various sites and inputting their own information. Now, various electronic devices are accumulating many different kinds of data. So many processors are brought to the data to process these data. The framework used to process these data is called Hadoop.
Hadoop is an open source software project that enables the distributed processing of large data sets across clusters of commodity servers. Hadoop is very scalable since new data can be added as needed without needing to change data formats. It is also very cost effective since it uses parallel computing and decrease the cost of storage. Hadoop can store any type of data, be it structured or unstructured from any types of sources. It is also fault tolerant as the system redirects work to another location of data and continues processing it whenever a node is lost. Hadoop is basically used to store massively large amount of data and to process these data at a much faster speed.
It is advised that you learn the Hadoop framework since the post of Data Analyst is one of the most reputed in Computer Science domain and it will be in strong demand in coming years. According to umbel.com the big data revenue has nearly quadrupled in the last three years and shows no signs of slowing down. This is because hardware costs are falling dramatically as software and services make up an increasing part of big data revenue. It is in strong demand because more and more businesses are getting into big data game.
It does not have a competitor since more enterprises will adopt a data driven business and will look to Hadoop to support their growth. The focus on Hadoop is only going to create more opportunities for new entrants in the market, to rise and solve its challenges. The eweek.com predicts that by 2020, Hadoop will be used by world-class enterprises, as well as businesses of all sizes for managing, processing and leveraging data to serve their better.
Hadoop works by providing a thin abstraction over local data storage and synchronization, allowing programmers to concentrate on writing code for analyzing the data. Besides Hadoop, it is also advised that you learn a tool called Ambari. It is a tool that can be used to provision, manage and monitor a cluster of Hadoop jobs.
Many big companies such as Yahoo, Amazon, Facebook and Twitter are using Hadoop. Companies such as Platfora, Alpine Data Labs and Altiscale are the hot Hadoop startups based in California, says cio.com.
In short, learning Hadoop will gain you Statistical Analysis and Data Mining skills, which is one of the top skills that the recruiters are looking for. Also, by looking at Hadoop job trends on indeed.com, it can be seen that there is a huge rise in the amount of job postings. Hence in the coming years, Hadoop will be the future of the big data in the enterprise.
