Big data, a platform in which everybody wants to gain knowledge on processing and analyzing the vast amount of data with ease. Various application are available today for processing vast amount of data and get the intended result from it, And various application testing tools are available to test the Big Data application. But no application or tool explain how data is validated before processing and after processing of data. Various existing functional and non-functional testing can be performed to assure the quality of the data so that the cost and time can be saved for the processing party. Here in this paper we are going to propose a set of testing strategies at various stages on Big Data analysis process so that one can validate data before retrieving the vast amount of data from Hadoop. © IAEME Publication.
