Spark通訊錄相似度計算怎么實現(xiàn)

發(fā)布時間:2021-12-08 14:33:47 來源:億速云 閱讀:175 作者:iii 欄目:大數(shù)據(jù)

本篇內(nèi)容介紹了“Spark通訊錄相似度計算怎么實現(xiàn)”的有關(guān)知識,在實際案例的操作過程中,不少人都會遇到這樣的困境,接下來就讓小編帶領(lǐng)大家學(xué)習(xí)一下如何處理這些情況吧!希望大家仔細閱讀,能夠?qū)W有所成!

需求:

Hive表中存有UserPhone跟LinkPhone 兩個字段。 通過SparkSQL計算出UserPhone之間通訊錄相似度>=80%的記錄數(shù)據(jù)。

相似度 = A跟B的交集/A的通訊錄大小。

pom文件

注意依賴之間的適配性,選擇合適的版本。同時一般可能會吧Hive中conf/hive-site.xml配置文件拷貝一份到 IDEA目錄
