Research on distributed data stream clustering algorithm based on Hadoop mapreduce Cai Binlei Ningjiadong Zhu Shiwei Guo Qin with the continuous increase of data flow scale, the existing clustering algorithm based on grid has no effect on the clustering of data streams, can not find any shape clusters in real time, and can not delete the noise points in the data stream in time. This paper presents a distributed data stream clustering algorithm (Pgdc-stream) based on grid density in Hadoop platform environment, which facilitates the parallel clustering of data flow in MapReduce framework based on Hadoop.
