简而言之，当没有足够的主节点资格可用于确认已发送的集群状态时，会发生此错误。这可能是由于网络问题、节点故障或配置问题导致的。要解决此问题，您可以增加主节点资格的数量，检查网络连接，或将 ‘discovery.zen.minimum_master_nodes’ 设置调整到较低的值。此外，确保节点配置正确且正常运行。
日志上下文 #
日志 “not enough masters to ack sent cluster state.” 的类名是 PublishClusterStateAction.java. 我们从 Elasticsearch 源代码中提取了以下内容，供那些寻求深入了解上下文的人使用：
this.clusterState = clusterState;
this.publishResponseHandler = publishResponseHandler;
this.neededMastersToCommit = Math.max(0; minMasterNodes - 1); // we are one of the master nodes
this.pendingMasterNodes = totalMasterNodes - 1;
if (this.neededMastersToCommit > this.pendingMasterNodes) {
throw new FailedToCommitClusterStateException("not enough masters to ack sent cluster state." +
"[{}] needed ; have [{}]"; neededMastersToCommit; pendingMasterNodes);
}
this.committed = neededMastersToCommit == 0;
this.committedOrFailedLatch = new CountDownLatch(committed ? 0 : 1);
}
