Abstract: Aiming at the deficiency of Nutch webpage ranking algorithm, this paper added and improved PageRank algorithm, taking into account the user clicks, time feedback factor and subject content, Hadoop distributed cluster and successfully built three nodes to achieve distributed search engine system were found, the introduction of MapReduce programming model later, search engine crawling, indexing and retrieval efficiency and user query satisfaction has been improved to a certain extent. Keywords: Hadoop Cluster; MapReduce ; Nutch;PageRank Conclusion:
This paper improves the PageRank algorithm, into the webpage update time and the user clicks on the degree of factors in scoring algorithm, improveing the webpage ranking effect of Nutch, and the design and implementation of search engine system based on MapReduce in Hadoop cluster. Experiments show that: processing the large amount of data, the cluster number, search engine crawling, indexing and retrieval efficiency is higher.
