我想将字符串数据从配置单元导出到oracle中的clob。
命令： sqoop export -Dsqoop.export.records.per.statement=1 --connect 'jdbc:oracle:thin:@192.168.41.67:1521:orcl' --username ILABUSER --password impetus --table ILABUSER.CDT_ORC_1 --export-dir /user/dev/db/123 --input-fields-terminated-by '\001' --input-null-string '\\N' --input-null-non-string '\\N' -m 2 例外情况：
