orientdb 로컬 노드가 아닌 마스터

Question

우리는 Java API 라이브러리가있는 노드가 5 개인 클러스터에서 OrientDB를 사용하고 있습니다. 둘 다 버전 2.2.8을 사용하고 있으며 Tinkerpop Blueprints 버전 2.6.0을 사용하고 있습니다. 데이터베이스가 오랫동안 정상적으로 작동하는 이상한 문제가 발생하고 갑자기 아래 오류가 발생하기 시작합니다. 1.7에서 2.2로 업그레이드 한 이후로만이 문제가 발생하기 시작했습니다.

이전에 다른 사람이이 문제/오류를 경험했는지 또는 누군가가 다중 노드 환경을 작동시키기 위해 변경해야 할 사항에 대해 조언을 해 주 었는지 궁금합니다.

Answer 1

2 노드 시나리오에서 비슷한 것을 보았습니다.

com.orientechnologies.orient.server.distributed.ODistributedConfigurationChangedException: Local node 'node1' is not the master for cluster 'event_3' (it is 'node2')

    at com.orientechnologies.orient.core.record.impl.ODocument.save(ODocument.java:1791) 
    (... stack trace truncated here ...) 

예외가 발생

자바 코드 :

OPartitionedDatabasePool pool = new OPartitionedDatabasePool(dbUrl, user, password); 
    ... 
    try (ODatabaseDocumentTx ignored = pool.acquire()) { 
     ODocument document = new ODocument(className); 
     document.fromJSON(recordData.encode()); 
     document.field("date", timestamp, OType.DATETIME); 
     document.save(); 
    } 

클러스터를 나열하는 클러스터 'event_3가'실제로 노드 2가 소유하고 있음을 보여줍니다 노드 1에 문서 (자바 API를) 절약에, 나는 오류를 얻을 :

|# |NAME  | ID|CLASS  |CONFLICT-STRATEGY|COUNT|OWNER_SERVER|OTHER_SERVERS|AUTO_DEPLOY_NEW_NODE| 
|14 |event_1  | 18|event  |     | 1| node1  | [node2] |  true  | 
|15 |event_2  | 19|event  |     | 1| node1  | [node2] |  true  | 
|16 |event_3  | 20|event  |     | 0| node2  | [node1] |  true  | 

삽입이 다른 경우에 성공하므로 특정 경우에만 삽입하기 위해 잘못된 노드가 선택된 것처럼 보입니다.
