STRING 데이터를 하이브에서 오라클의 CLOB으로 내보내려고합니다.Sqoop 하이브 문자열을 Oracle CLOB로 내보내기
명령 :
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
예외 : 나는 --map-column-java 태그를 사용하는 해결 방법으로
