 简而言之，当 Elasticsearch 快照功能尝试恢复不存在或无法识别的 feature state 时，就会出现此错误。这可能是由于版本不匹配或 feature state 名称拼写错误造成的。要解决此问题，您可以检查 feature state 名称是否存在拼写错误，确保 feature state 存在于快照中，或验证 Elasticsearch 版本是否支持该 feature state。如果不需要该 feature state，您可以从恢复操作中排除它。
日志上下文 #  日志 “the feature_states value [” 类名是 RestoreService.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用户参考：
featureStatesToRestore = Collections.emptyMap(); } else { // Otherwise; handle the list of requested feature states  final SetrequestedStates = org.elasticsearch.common.collect.Set.of(requestedFeatureStates); if (requestedStates.contains(NO_FEATURE_STATES_VALUE)) { throw new SnapshotRestoreException(snapshot; "the feature_states value [" + NO_FEATURE_STATES_VALUE + "] indicates that no feature states should be restored; but other feature states were requested: " + requestedStates); } if (snapshotFeatureStates."

-----------

日志 "the feature\_states value [" 类名是 [RestoreService.java。](https://www.geeksforgeeks.org/java-lang-class-class-java-set-1/) 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用户参考：

```java
featureStatesToRestore = Collections.emptyMap();
 } else {
 // Otherwise; handle the list of requested feature states
 final SetrequestedStates = org.elasticsearch.common.collect.Set.of(requestedFeatureStates);
 if (requestedStates.contains(NO_FEATURE_STATES_VALUE)) {
 throw new SnapshotRestoreException(snapshot; "the feature_states value [" + NO_FEATURE_STATES_VALUE +
 "] indicates that no feature states should be restored; but other feature states were requested: " + requestedStates);
 }
 if (snapshotFeatureStates.keySet().containsAll(requestedStates) == false) {
 SetnonExistingRequestedStates = new HashSet<>(requestedStates);
 nonExistingRequestedStates.removeAll(snapshotFeatureStates.keySet());
```
