Question

我按照“说明”here（文档不太好！）。基本上，我在sqoop.properties和catalina.properties中设置了一堆路径。

但是在sqoop.sh server start上，日志显示找不到文件审计记录器类。我复制了一堆jar文件，但仍然没有运气！

您没有指定，但假设您使用hadoop2，则需要将以下jar位置添加到common.loader属性

/ usr / lib中/ hadoop的/ *。罐
/ usr / lib中/ hadoop的/ lib中/ *。罐
/ usr / lib中/ Hadoop的MapReduce的/ *。罐
/ usr / lib中/ Hadoop的纱线/ *。罐
/ usr / lib中/ Hadoop的HDFS / *。罐

common.loader=${catalina.base}/lib,${catalina.base}/lib/*.jar,${catalina.home}/lib,${catalina.home}/lib/*.jar,${catalina.home}/../lib/*.jar,/usr/lib/hadoop/*.jar,/usr/lib/hadoop/lib/*.jar,/usr/lib/hadoop-mapreduce/*.jar,/usr/lib/hadoop-yarn/*.jar,/usr/lib/hadoop-hdfs/*.jar

Sqoop2可以找到Audit LoggerManager
