With rapid growth of development in healthcare applications,large amount of heterogeneous data are generated by healthcare organizations. It is very difficult to process the huge volume of data by using traditional data processing systems. Healthcare applications are being supplied through internet and cloud services rather than using a traditional software. Without applying proper data analytics methods, these data became useless. The data need to be processed and analyzed effectively for better decision making. The critical challenge that the healthcare organizations are facing is, how to analyze the large-scale data. In this paper we discuss on introduction to the big data characteristics, to process and analyze large scale healthcare data using Hadoop on cloud computing environment.
