헥터 & 카산드라 문제 NoSuchFieldError : DEFAULT_MEMTABLE_THROUGHPUT_IN_MB

Question

헥터를 통한 카산드라 데이터베이스 연결을 테스트하고 있습니다.

java.lang.NoSuchFieldError : DEFAULT_MEMTABLE_THROUGHPUT_IN_MB

누군가가 내가 잘못 무엇을 알고 있나요 내가 JUnit 테스트를 실행할 때하지만 constanly 다음과 같은 메시지가? 당신의 도움에 대한

감사합니다, 여기에 코드

그리고 크리스 : 당신이 헥터와 카산드라의 호환되지 않는 버전을 사용하는 것처럼

보인다. memtable flushing을 튜닝하는 파라미터 (DEFAULT_MEMTABLE_THROUGHPUT_IN_MB 등)는 튜닝 프로세스를 간소화하기 위해 최신 버전에서 변경되었습니다. 당신이 사용하고있는 헥터와 카산드라의 버전을 정확하게 말할 수 있다면, 상황이 더 명확해질 수 있습니다 ...
