Apache Ignite 구성 오류

Question

4 노드 Apache Ignite Cluster를 빌드하고 Java 프로그램에서 캐시를 생성하는 것과 같은 기본 작업을 수행하고 연결할 수 있습니다.

하지만 MySQL 통합을 수행 할 때 Ignite 클러스터에 연결되지 않습니다.

다음은 오류 메시지입니다.

은 Ignite 구성 파일은 다음?

Answer 1

오류는 다음과 같이 변경하여 해결되었습니다

• 추가
• 보장 된 클러스터 설정 파일 및 클라이언트 설정 파일이 동일 점화 libs와 디렉토리의 최신 MySQL의 JDBC 항아리 (이전 클라이언트 설정 파일 추가 몇 포함 캐시 구성의 구성).
• Person 클래스 (Ignite 캐시에 저장되는 MySQL 테이블 POJO)가 추가되었습니다.
