Abstract
In view of the subjectivity, lagness and singleness of metric of the decision threshold in the default load balancing strategy of HDFS cluster, by analyzing the characteristics of HDFS clustering architecture, HDFS cluster processing objects and the cluster itself dynamic real-time changes, combined with some of the load balancing strategy threshold improvement algorithm,this paper presented a prediction model based on the estimated file attributes combined with cluster attributes comprehensive calculation threshold method.The threshold calculated by this method was substituted into the corresponding load balancing strategy for load optimization.The experimental results showed that the proposed method based on the estimated model to estimate the file attributes had high accuracy and the load balancing strategy based on the prediction model was efficient in adjusting the load of the cluster.At the same time,it could further shorten the execution time of cluster operations and improved the efficiency of cluster operations.关键词
