Vandana Malik · International Journal for Research in Applied Science and Engineering Technology · 2020
Hadoop is an open-source software framework for storing data and running applications on clusters of commodity hardware.It provides massive storage for any kind of data, enormous processing power and the ability to handle virtually limitless concurrent tasks or jobs.It is one of the tools designed to handle big data.Therefore, in recent years, with the popularization of the concept and application of cloud computing, it is focused on more and more by academia circles and industrial circles also.Hadoop is fundamentally meant to distribute storage & processing of Big Data sets on clusters of computer systems created on commodity hardware and it is an open source software framework.While designing the modules for Hadoop, one basic assumption is made that failures occurring in the hardware are common and framework would handle them all automatically.The biggest challenge in utilizing Hadoop to its full potential is the wisdom of knowing that where it can be used and where not.With the growing acceptance of Hadoop, there is an increasing trend to incorporate more and more enterprise security features.Therefore, the present research paper highlights the security challenges in Hadoop system.
