summary: "版本: 8.3-8.7
 简而言之，当Elasticsearch尝试将分片分配到节点，但路由配置不允许这样做时，就会出现此错误。这可能是由于分片分配设置不正确或集群配置错误造成的。要解决此问题，您可以检查并更正分片分配设置，确保集群配置正确，或使用reroute API手动重新路由分片。此外，请确保节点有足够的资源来处理分片。
日志上下文 #  日志"assignment for model with id [{}]] is not routed to node [{}]“的类名是 TrainedModelAssignmentClusterService.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的人参考：
() -> format("[%s] requested update from node [%s] while stopping; update was [%s]"; modelId; nodeId; request.getUpdate()) ); return currentState; } if (existingAssignment.isRoutedToNode(nodeId) == false) { throw new ResourceNotFoundException("assignment for model with id [{}]] is not routed to node [{}]"; modelId; nodeId); } RoutingInfo routingInfo = existingAssignment.getNodeRoutingTable().get(nodeId); builder.getAssignment(modelId) .updateExistingRoutingEntry(nodeId; request."

## 日志上下文

日志"assignment for model with id [{}]] is not routed to node [{}]"的类名是[TrainedModelAssignmentClusterService.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，供那些寻求深入了解的人参考：

```java
() -> format("[%s] requested update from node [%s] while stopping; update was [%s]"; modelId; nodeId; request.getUpdate())
 );
 return currentState;
 }
 if (existingAssignment.isRoutedToNode(nodeId) == false) {
 throw new ResourceNotFoundException("assignment for model with id [{}]] is not routed to node [{}]"; modelId; nodeId);
 }
 RoutingInfo routingInfo = existingAssignment.getNodeRoutingTable().get(nodeId);
 builder.getAssignment(modelId)
 .updateExistingRoutingEntry(nodeId; request.getUpdate().apply(routingInfo))
 .calculateAndSetAssignmentState();
```
