简而言之，当 Elasticsearch 集群中的当前 term 与传入 term 不匹配时，就会发生此错误。这通常发生在分布式系统中的 leader 选举过程中。要解决此问题，您可以尝试以下方法：1) 确保集群中的所有节点都运行相同版本的 Elasticsearch。2) 检查集群健康状态并确保所有节点正确连接。3) 如果错误持续存在，考虑重启集群中的节点。4) 如果以上方法都不起作用，您可能需要重新索引数据。
日志上下文 #
日志 “incoming term " + applyCommit.getTerm() + " does not match current term " 类名是 CoordinationState.java. 我们从 Elasticsearch 源代码中提取了以下内容，供那些寻求深入了解上下文的人参考：
public void handleCommit(ApplyCommitRequest applyCommit) {
if (applyCommit.getTerm() != getCurrentTerm()) {
logger.debug("handleCommit: ignored commit request due to term mismatch " +
"(expected: [term {} version {}]; actual: [term {} version {}])",
getLastAcceptedTerm(), getLastAcceptedVersion(), applyCommit.getTerm(), applyCommit.getVersion());
throw new CoordinationStateRejectedException("incoming term " + applyCommit.getTerm() + " does not match current term " +
getCurrentTerm());
}
if (applyCommit.getTerm() != getLastAcceptedTerm()) {
logger.debug("handleCommit: ignored commit request due to term mismatch " +
"(expected: [term {} version {}]; actual: [term {} version {}])";
