Oozie sqoop任务错误：无法运行程序＆＃34; hive＆＃34;：error = 2没有这样的文件或目录

Question

我创建了一个oozie sqoop任务，用于将数据从mysql导入到hive。我有一个namenode和3个datanode，它们还在namenode上安装了hive，oozie和sqoop。

sqoop import coommand已在namenode上测试了var CLI，但每次我创建一个oozie sqoop任务时，它也会失败。以下是详细错误。

这是我的想法

1. 生成映射器作业，因此应该提交此脚本并在namenode上运行。这是对的吗？
2. 我所有的env vars配置都很好，所以错误阶段，导入数据到hive表的导入工具应该在其中一个datanode上启动。

我应该在群集的每个datanode上安装配置单元吗？或者我可以做任何配置来解决这个问题吗？

Answer 1

1. 确保hdfs中存在hive-site.xml。
2. 将所有hive libs共享文件夹复制到sqoop libs共享文件夹。
