Question

使用target-dir时，为什么--import-all-tables无效？

sqoop import-all-tables --connect jdbc:mysql://localhost/retail_db --username root --password cloudera --warehouse-dir /user/cloudera/retail_db

sqoop import-all-tables --connect jdbc:mysql://localhost/retail_db --username root --password cloudera --target-dir /user/cloudera/retail_db

错误日志;

请查看Sqoop用户指南： https://sqoop.apache.org/docs/1.4.1-incubating/SqoopUserGuide.html

默认情况下，当发出一个import-all-tables命令时，它将导入到当前用户的hdfs主文件夹：

即： sqoop import-all-tables --connect jdbc：mysql：// localhost / retail_db --username root --password cloudera --target -dir / user / cloudera /

或以下也可以，它只会导入到/ user / cloudera /：

sqoop import-all-tables --connect jdbc：mysql：// localhost / retail_db --username root --password cloudera

但是在你的情况下，你使用的是另一个目的地，除了你的家庭目录，因此--warehouse-dir将在这里使用：

sqoop import-all-tables --connect jdbc：mysql：// localhost / retail_db --username root --password cloudera --warehouse-dir / user / cloudera / retail_db

--Warehouse-dir工作但目标-dir错误
