Sqoop错误

1. 导入时使用`--split-by`出错

19/12/01 17:13:17 ERROR tool.ImportTool: Import failed: java.io.IOException: Generating splits for a textual index column allowed only in case of "-Dorg.apache.sqoop.splitter.allow_text_splitter=true" property passed as a parameter

出现以上问题，说明要进行切分的字段不是数据类型的类型
解决方法：
①将要导入的表中的字段修改为数据类型
②将-Dorg.apache.sqoop.splitter.allow_text_splitter=true添加在import命令后面

2. Sqoop导入Hive出错
