hive schema설정없이 hive를 최초에 실행했을때 발생하는 오류메세지및 처리방법

총관리자 2016.09.25 10:33 조회 수 : 1228

./schematool -initSchema -dbType derby 를 실행해준다.

(-dbType은  derby|mysql|postgres|oracle중에 하나를 지정해준다.)


schematool실행시 오류가 발생하여 다시 schematool -initSchema를 실행할때 "Error: FUNCTION 'NUCLEUS_ASCII' already exists. (state=X0Y68,code=30000)"오류가 발생하는데 이때는 "ls -l | grep meta"로 metastore_db폴더를 찾아 삭제하고 schematool을 이용하여 initSchema를 수행하면 정상적으로 schema가 초기화 된다.
