은 Ignite 서버 노드 아래 예외를 던졌다 ignitevisorcmd.sh를 사용하여 작업을 실패한 후. 모든 서버 노드는 정상이지만 노드 서버가 다운 된 경우도있었습니다. 왜 이렇게 행동했는지 나는 몰랐다.
도움을 주시면 감사하겠습니다.

답장을 보내 주셔서 감사합니다. 네트워크는 괜찮습니다. 노드 중 하나가 다운 될 때마다 발생하지 않았습니다. 작은 데이터 세트의 경우 작업이 항상 올바르게 완료됩니다. –
메모리가 부족하지 않습니까? – Dmitriy
No. 데이터 파일은 약 25.3GB이고 총 서버 노드 jvm 힙은 16GB 인 48GB입니다. –
