简要来说，当 Elasticsearch 中的节点尝试成为主节点但失败时，会出现此错误。这可能是由于网络问题、配置问题或更高优先级的节点接管导致的。要解决此问题，请确保所有节点都正确配置且网络连接稳定。此外，检查主节点的优先级设置。如有必要，调整 ‘discovery.zen.minimum_master_nodes’ 设置以避免脑裂场景。
日志上下文 #
日志 “election not won” 的类名是 CoordinationState.java。我们从 Elasticsearch 源代码中提取了以下内容，供那些寻求深入上下文的人使用：
* @throws CoordinationStateRejectedException if the arguments were incompatible with the current state of this object.
*/
public PublishRequest handleClientValue(ClusterState clusterState) {
if (electionWon == false) {
logger.debug("handleClientValue: ignored request as election not won");
throw new CoordinationStateRejectedException("election not won");
}
if (lastPublishedVersion != getLastAcceptedVersion()) {
logger.debug("handleClientValue: cannot start publishing next value before accepting previous one");
throw new CoordinationStateRejectedException("cannot start publishing next value before accepting previous one");
}
