> *Description:*
>  # Ctrl + C to stop a running DataNode
>  # `show cluster` shows that the DataNode is ReadOnly
>  # the write towards this DataNode won't be rejected
> *Analysis:*
> When using Ctrl+C to stop a DataNode, the shutdownhook will be invoked. And, inside the shutdown hook, the DataNode is setting to status `Stopping` and `Readonly`. 
> Because of the change of PR [https://github.com/apache/iotdb/pull/9274/files,]  the isReadOnly() will return false in DataRegionStatemachine, which won't reject the write operations.
