> In  {{RSRpcServices.executeProcedures}} , we use tdCache to  avoid reading from the {{TableDescritor}} every time(usually it will read from the file system), just as following line 3923 :
> {code:java}
> 3914 public ExecuteProceduresResponse executeProcedures(RpcController controller,
> 3915     ExecuteProceduresRequest request) throws ServiceException {
> 3916   try {
> 3917     checkOpen();
> 3918     throwOnWrongStartCode(request);
> 3919      regionServer.getRegionServerCoprocessorHost().preExecuteProcedures();
> 3920      if (request.getOpenRegionCount() > 0) {
> 3921        // Avoid reading from the TableDescritor every time(usually it will read from the file
> 3922        // system)
> 3923        Map<TableName, TableDescriptor> tdCache = new HashMap<>();
> 3924        request.getOpenRegionList().forEach(req -> executeOpenRegionProcedures(req, tdCache));
> 3925      }
>    ......
> {code}
> but for {{RSRpcServices.executeOpenRegionProcedures}} in above line 3924, there is no place to fill the {{tdCache}}, so the {{tdCache}} does not take effect in fact.
