Big data refers to processing of enormous amount of unstructured data. The MapReduce and Hadoop are open-source softwares for bigdata applications.The unstructured data are processed using MapReduce framework and Hadoop as an environment, providing distributed file storage for absolute blobs of data. The intermediate data generated are left unstored and hindered in MapReduce framework. Dache refers a cache imbibing the data that is accessed through a request and reply protocol. In this paper, we propose an effective technique for enhancing the performance of Dache by introducing a cache optimization algorithm and a better page replacement technique.
