简而言之，当 Elasticsearch 集群中之前作为特定分片领导者的节点失去其领导者状态时，就会发生此错误。这可能是由于网络问题、节点故障或新的领导者选举所致。要解决此问题，您可以尝试以下操作：1) 检查节点和网络的健康状况，2) 确保集群有足够的资源来处理负载，3) 检查分片分配设置以防止频繁的领导者选举，4) 如果问题是由网络缓慢或节点过载引起的，请考虑增加超时设置。
日志上下文 #
日志"no longer leading this publication’s term:“类名是 Coordinator.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参考：
logger.trace("handlePublishRequest: handling [{}] from [{}]", publishRequest, sourceNode);
if (sourceNode.equals(getLocalNode()) && mode != Mode.LEADER) {
// Rare case in which we stood down as leader between starting this publication and receiving it ourselves. The publication
// is already failed so there is no point in proceeding.
throw new CoordinationStateRejectedException("no longer leading this publication's term: " + publishRequest);
}
final ClusterState localState = coordinationState.get().getLastAcceptedState();
if (localState.metadata().clusterUUIDCommitted())
