摘要Abstract: We presented the author’s SMCCSE (Social Media
Cloud Computing Service Environment) that supports the
development and construction of Social Networking Service
(SNS) based on large amounts of social media including audio,
video and image in earlier publication. The main contributions
of this paper are to present how to design and implement
MapReduce-based image conversion module for social media
transcoding and transmoding that are the core functions in our
SMCCSE as well as to verify performance evaluation results
for image conversion module. In this paper, we show a
partially functional image conversion module based on Hadoop
in SMCCSE except for video and audio. Moreover, we discuss
experimental results performed on a 28 node SMCCSE cluster
under varying experimental conditions in order to verify the
performance for image conversion function.
