Performance Evaluation of a Hadoop-based Distributed Video Transcoding System for Mobile Media Service
نویسندگان
چکیده
Previously, we proposed a Hadoop-based Distributed Video Transcoding System that transcodes a large number of video data sets into specific video formats depending on user-requested options. In order to reduce the transcoding time exponentially, we apply a Hadoop Distributed File System (HDFS) and a MapReduce framework to our system. Hadoop and MapReduce are designed to process petabyte-scale text data in a parallel and distributed manner, while our system processes multi-media data. In this study, we measure the total transcoding time for various values of three MapReduce tuning parameters: block replication factor, Hadoop Distributed File System block size, and Java Virtual Machine reuse option. Thus, we determine the optimal values of the parameters affecting transcoding performance.
