我已经命令将sql从sqlserver导入到hive，如下所示
sqoop import --connect 'jdbc:sqlserver://10.0.2.11:1433;database=SP2010' --username pbddms -P --table daily_language --hive-import --hive-database test_hive --hive-table daily_language --hive-overwrite --hive-drop-import-delims --null-string '\\N' --null-non-string '\\N'
但结果却是如此

为什么会这样
ERROR tool.ImportTool：遇到IOException正在运行导入作业：java.io.IOException：仅在“-Dorg.apache.sqoop.splitter.allow_text_splitter = true”属性作为参数传递的情况下，才允许为文本索引列生成拆分
虽然我不在上面的sqoop导入中给出split-by。首先，我如何解决上述情况？
然后我尝试在上面的sqoop导入中添加“-Dorg.apache.sqoop.splitter.allow_text_splitter = true”，但它在下面给出了另一个错误;

第二种情况，我怎么能解决上面的情况？
我把kdbahasa列作为分离列。添加-m 1参数以指定映射器的数量。 1 - 意味着它将在没有拆分的单个映射器上运行：
sqoop import --connect 'jdbc:sqlserver://10.0.2.11:1433;database=SP2010' --username pbddms -P --table daily_language --hive-import -m 1 --hive-database test_hive --hive-table daily_language --hive-overwrite --hive-drop-import-delims --null-string '\\N' --null-non-string '\\N'
如果要拆分，请阅读有关split_column的内容：https://stackoverflow.com/a/37389134/2700344
