With the world of online activity buzzing with millions of users across the world logging in every few seconds and copious amounts of data being exchanged every millisecond; database management has emerged as one of the biggest challenges for system administrators. Traditional models of database management, though quite effective, are nowhere near capable enough for handling such volumes of data as in circulation today. This underlined the need for more efficient systems that could handle data volumes more competently and provide fail safes for the users and gave birth to Hadoop which stands for High-availability distributed object-oriented platform. Hadoop is basically a database management system that allows for processing of large volumes of data at different nodes or clusters of systems distributing the processing and making use of the computing capabilities and storage space of the individual machines. The ability to detect and repair failures is inherently embedded in the software itself so that there are virtually no downtime as in case of single server units. Hadoop is making it big in data management circles these days with lots of social networking and search platforms now providing customized searches and user data trends analytics. This is probably one of the biggest areas of applications for such extensive software too, apart from many other applications like financial markets and online markets to name a few. With Hadoop such a big thing in the online community today, there are only a few who actually understand the system and can apply that knowledge skilfully for benefit. The Job Opportunity in Hadoop has reached their Maximum Requirement and if we talk about professional in this Technology the Still is few person Group are having knowledge of this.
