TApplicationException：必填字段「client_protocol」未設置

Question

我開發一個節儉的客戶，

我有我的機器上建立一個節儉蜂巢服務器（Apache的蜂房0.14.0）和我也有機會獲得Cloudera的DIST蜂巢4.6.0

當我節儉客戶端連接到客戶端CDH給予以下錯誤：

TApplicationException: Required field 'client_protocol' is unset! 
Struct:TOpenSessionReq(client_protocol:null, username: 

我傳遞正確的協議服務器，但它似乎有些事情是在騎它... 。

而且如果我點到本地主機（在那裏我有我的蜂巢服務器上運行）的每一件事似乎做工精細....

請讓我知道什麼是錯在這裏....

代碼：

 var socket = new TSocket("XXX.XXX.XXX.XXX", 10000); 

     TStreamTransport sTransport = (TStreamTransport)socket; 

     var transport = new TBufferedTransport(socket); 

     underlyingTransport = transport; 

     var proto = new TBinaryProtocol(transport); 
     var client = new TCLIService.Client(proto); 
     transport.Open(); 

     TOpenSessionReq req = new TOpenSessionReq(TProtocolVersion.HIVE_CLI_SERVICE_PROTOCOL_V6); 
     req.Username = "hive"; 
     req.Password = "hive"; 

     TOpenSessionResp oSResponse = client.OpenSession(req); 
     TSessionHandle sessionHandle = oSResponse.SessionHandle; 

     TExecuteStatementReq execReq = new TExecuteStatementReq(sessionHandle, "select * from emp"); 
     TExecuteStatementResp exeRes= client.ExecuteStatement(execReq); 
     TOperationHandle operationHandle = exeRes.OperationHandle; 

     TFetchResultsReq fechReq = new TFetchResultsReq(operationHandle,TFetchOrientation.FETCH_FIRST, 1); 
     TFetchResultsResp fechRes = client.FetchResults(fechReq); 

     TRowSet results = fechRes.Results; 
     List<TRow> resultRows = results.Rows; 
     foreach (var row in resultRows) 
     { 
      var val = row.ColVals[0]; 
      System.Console.WriteLine(val.StringVal); 
     } 

     TCloseOperationReq closeOprReq = new TCloseOperationReq(operationHandle); 
     client.CloseOperation(closeOprReq); 

     TCloseSessionReq creq = new TCloseSessionReq(sessionHandle); 
     client.CloseSession(creq);

我相信這是蜂巢-JDBC的版本問題。此解決方案可能會解決您的問題：Required field 'client_protocol' is unset
