This research checks effectiveness of test of a single computer (CPU I5-4440 3.1 GHz and 8G memory). And tests the use of Raspberry Pi3 erected six groups of Hadoop clusters. This study puts forward setup clusters called Hadoop on the new SBC (Single-Board Computer) Raspberry Pi. This Hadoop cluster provides computing and storage services. Pattern recognition was run on the SBC clusters and the single computer; they are similar in price; their performance was observed. It is revealed the SBC clusters were better than single computers in performance that were increased by about 20% and increased number of SBC can improve cluster processing speed. In this research, experimental data were apparent, and Hadoop was used by Hadoop Distributed File System (HDFS) in the data storage; it has better security than a single computer. This research can be used as Hadoop infrastructure in the future.
