简要来说，当 Elasticsearch 中的传入术语与上次接受的术语之间存在不匹配时，会发生此错误。这通常在集群状态更新期间或新节点尝试加入集群时发生。要解决此问题，您可以尝试以下方法：1）重启导致错误的节点。2）检查集群健康状况，确保所有节点同步。3）如果错误仍然存在，您可能需要从集群中移除有问题的节点，然后重新添加它。
日志上下文 #
日志 “incoming term " + applyCommit.getTerm() + " does not match last accepted term " 的类名是 CoordinationState.java. 我们从 Elasticsearch 源代码中提取了以下内容，供那些寻求深入了解上下文的人参考：
}
if (applyCommit.getTerm() != getLastAcceptedTerm()) {
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 last accepted term " +
getLastAcceptedTerm());
}
if (applyCommit.getVersion() != getLastAcceptedVersion()) {
logger.debug("handleCommit: ignored commit request due to version mismatch (term {}; expected: [{}]; actual: [{}])";
getLastAcceptedTerm(); getLastAcceptedVersion(); applyCommit.getVersion());
