Implementation of Hadoop Based Framework for Parallel Processing of Biological Data

Praveen Kumar B | Nirmala Bariker

Abstract: Bioinformatics is challenged by the fact that traditional analysis tools have difficulty in processing large-scale datafrom high-throughput sequencing. Hadoop is designed to process large data sets (petabytes). It becomes a bottleneck, when handling massive small files because the name node utilize more memory to store the metadata of files and the data nodes consumes more CPU time to process massive small files. The open source Apache Hadoop project, which in this paper, presenting the Optimized Hadoop, consists of Merge Model to merge massive small files into a single large file and introduced the efficient indexing mechanism and adopts the MapReduce frame-work using decision classification rule for analysis and Diagnosis of Iris Plants data through a distributed file system to achieve scalable, efficient and reliable computing performance on Linux clusters of low cost commodity machines. Our experimental result shows that Optimized Hadoop improves performance of processing small files drastically up to 90.83 % and effectively reduces the memory utilization of the name node to store the metadata of files.
