我正在尝试使用自由格式查询运行sqoop命令，因为我需要执行聚合。它是通过Hue界面提交的，作为Oozie工作流程。以下是命令和查询的缩小版本。处理命令时，＆＃34; - 查询＆＃34;语句（括在引号中）导致查询的每个部分都被解释为无法识别的参数，如命令后面的错误所示。此外，目标目录被误解释。是什么阻止了它的运行，以及可以采取哪些措施来解决它？ $ {env}和$ {shard}变量正在被正确解析，如上一条错误消息所示。
谢谢！

我能够让这个工作。解决方案是将所有查询元素作为单独的参数提交。什么不应该在＆＃34;命令＆＃34;窗口。相反，从＆＃34; import＆＃34;开始作为第一个参数，输入查询的每个部分作为单独的参数。每个元素的属性和值作为单独的参数输入。例如：
arg: import arg: --connect arg: jdbc:mysql.... arg: --username arg: [username] arg: --password-file arg: [password file] arg: --query arg: select ..... arg: --target-dir arg: [target]
工作流程按预期执行。
