TApplicationException：必填字段“client_protocol”未设置

Question

我开发一个节俭的客户，

我有我的机器上建立一个节俭蜂巢服务器（Apache的蜂房0.14.0）和我也有机会获得Cloudera的DIST蜂巢4.6.0

当我节俭客户端连接到客户端CDH给予以下错误：

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

我传递正确的协议服务器，但它似乎有些事情是在骑它... 。

而且如果我点到本地主机（在那里我有我的蜂巢服务器上运行）的每一件事似乎做工精细....

请让我知道什么是错在这里....

代码：

 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);

我相信这是蜂巢-JDBC的版本问题。此解决方案可能会解决您的问题：Required field 'client_protocol' is unset
