我正在尝试将 sqoop 作业作为 oozie 操作运行。我将 MySQL 作为 jobtracker 节点上的元存储。我在某处读到 oozie sqoop 无法通过导入创建配置单元表。所以我试图将数据转储到 hdfs 中。现在还是这样吗？

我检查了共享库。

我正在尝试从 MS SQL 数据库中获取 Sqoop。

当我运行不需要来自 shell 的元存储的 sqoop 命令时，它可以工作。

sqoop import --connect 'jdbc:sqlserver://host;username=sqoopimport;password=password;database=db1' --table t1--target-dir /user/root/sqoop-import/tmp/t1

当我尝试将其作为 sqoop 操作运行时出现此错误

我认为这是主要原因。我在共享库目录中有库 2285 [main] 错误 org.apache.sqoop.tool.BaseSqoopTool - 创建数据库管理器时出错:java.io.IOException:连接字符串没有管理器:

我错过了什么吗？感谢您的帮助。

谢谢， 阿比舍克

最佳答案

当您使用 shell(例如 Bash 或 ZSH)执行 Sqoop 时，您需要手动对参数进行转义，以便 shell 不会更改它们。在您的示例中，您已将 JDBC URL 放入引号中，这样分号就不会被解释为命令的结尾。由于 Oozie 不使用 shell 调用 Sqoop，因此这些转义字符无效。因此，您应该删除 oozie 工作流程中为 shell 引入的转义。

例如:

<command>import --connect jdbc:sqlserver://host;username=sqoopimport;password=password;database=db1 --table t1--target-dir /user/root/sqoop-import/tmp/t1</command>

另请注意，建议使用参数 --username 和 --password 而不是 JDBC URL 中的相同命名属性。
