| Abstract | The MapReduce framework is considered to be an effective resolution for huge and parallel data processing. This paper treats a massive data processing workflow as a DAG graph consisting of MapReduce jobs. In a heterogeneous computing environment, the computation speed can be different even on the same slot depending on various jobs. For this problem, this paper proposes an optimized MapReduce workflow scheduling algorithm. This algorithm comprises a job prioritizing phase and a task assignment phase. First, the jobs can be classified as I/O-intensive and computing-intensive, and the priorities of all jobs are computed according to their corresponding types. Then, the suitable slots are allocated for each block, and the MapReduce tasks in the workflow are scheduled with respect to data locality. The experimental results show that the optimized MapReduce workflow scheduling algorithm can improve the performance of task scheduling and the rationality of resources allocation in heterogeneous computing. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
