The use of big data in the real world was complicated. It may contain different characteristic of data and computing. In this case, the single computing mode was mostly difficult to met the application requirements. Therefore we need to consider different computing mode of mix use. The ultimate evolution of hybrid computing mode is spark system which invented by UCBerkeley AMPLab. It covers almost all the typical big data computing mode, including iterative computing, batch computing, memory computing, flow computing (Spark Streaming), data query analysis (Shark), and map computing (GraphX). Spark provides a powerful memory computing engine and implents computing with excellent performance, while maintaining compatibility with the Hadoop platform. Therefore, with the continuous stable and mature, Spark is expected to be colocalized with Hadoop and became a new generation of big data processing systems and platforms. The paper has studied and analyed the Spark ecosystem, and set up the hybrid computing model architecture based on Spark platform, which also has illustrated the spark ecosystem can meet the application of hybrid computing model.
