With the rapid development of embedded system and Internet of Things technology, embedded system and smart device based on embedded system is collecting huge amounts of data, and corresponding data processing and application method have been greatly changed, different from the traditional big data and cloud computing focus, local processing and application become important trend. This paper tries to take Cortex-A7 as the main system with the stronger ability, Hadoop distributed computing system is deployed in embedded system and could meet the demand of the future data process with directly managing the resource-constrained sensors, embedded systems and smart devices. Successfully deploying over 20GB data in the test, the system is verified that it can complete most of the functions of data processing cluster, and can also manage the collected sensors and embedded system terminal, with better research and market promotional value.
