나는 돼지 스크립트를 실행하지만 1200 오류를 반환, 그것은 뭔가처럼 보입니다 NullPointerException 오류. 다음은 스크립트와 오류입니다. 그것을 고치는 방법? 감사.돼지 스크립트 오류 1200 null
스크립트
A =로드 'HDFS : // URL/입력'PigStorage ('')를 사용 AS (ID : chararray 이름 : chararray)를;
B = foreach A는 id $ 0을 생성합니다.
B를 'hdfs : // tmp/output'에 저장하십시오.

제 마지막에 재현 한 결과 제대로 작동하는 것 같습니다. 몇 가지 샘플 데이터를 공유 할 수 있습니까? 그런 오류를해서는 안됩니다. 또한, 0.12에서 테스트 한 PIG 버전을 알려주십시오. 또한 돼지 스크립트를 실행하는 방법은 로컬 모드 또는 Mapreduce 모드입니다. –
안녕하세요, Rajnish, 나는 그것을 oozie에서 실행합니다. PIG 버전은 0.12입니다. 답장을 보내 주셔서 감사합니다. – alexqinbj
