可以让 wholeTextFiles 方法帮我们决定。 # 我在 files 目录中生成了 100 个小文件(每个文件里面只有一个字符串 "hello")# 如果使用 textFile 读取,那么 RDD 会有 100 个分区>>>rdd = sc.textFile("hdfs://satori001:9000/files")>>>rdd.getNumPartitions()100# 而使用 wholeTextFiles 读取,那么只有两...

该端口是ASR平台抓取AP和CP log的端口。 “Config file”是QWinLog抓取log所使用的配置文件,用户可以使用工具默认的配置文件或者联系我司FAE提供相关配置文件。 “Log path”为抓取的log保存路径,一般保持默认即可,用户也可根据需要修改。 步骤3:开始Log抓取 点击QWinLog界面的“Start”按钮开始抓取log,点击“Stop”按...
