Hadoop-Based Data Management Service for Cloud

In this paper we are going to discuss HadoopBased data management Service For Cloud. Data security issues and challenges in cloud computing, and also discuss environment used for data processing file management. In this paper we discuss architecture of hadoop also prominent users. Hadoop is an open-source software framework for storing and processing big data in a distributed fashion on large clusters of commodity hardware. Essentially, it accomplishes two tasks: massive storage and faster processing. Hadoop, a community driven Apache project has provided an efficient and cost effective platform for large scale computation using the map-reduce methodology, pioneered by Google. Hadoop capabilities are also extended in a quest for intelligent decision making regarding the choice of the fittest services for federation in a federated cloud scenario, in addition to legally behavior regarding the geographical location of data storage.&nbsp
