DESCRIBE EXTENDED show numRows=0
Hi, I have observed that DESCRIBE EXTENDED always shows number of rows to be zero despite the fact that the table has data. Is it a bug? Is it known ? Has anyone else also come across the same ? Thanks,
RE: HS2 ODBC incompatibility
Looking at some of the sample code in java implementation, can't figure out where I am going wrong. Is it possible to point out what is that I am doing wrong here ? It executes the select query fine at the server end ( looking at the logs), however, fetchRes->results.rows.size() turns out to be zero. // quer_str = "SELECT * FROM foo"; TOpenSessionReq *sessionReq = new TOpenSessionReq(); sessionReq->__set_client_protocol((TProtocolVersion::type)0); TOpenSessionResp *sessionRes = new TOpenSessionResp(); //TSessionHandle *sessionHandle = new TSessionHandle(); connection->client->OpenSession(*sessionRes, *sessionReq); TExecuteStatementReq *execStmtReq = new TExecuteStatementReq(); TExecuteStatementResp *execStmtRes = new TExecuteStatementResp(); execStmtReq->__set_sessionHandle(sessionRes->sessionHandle); execStmtReq->__set_statement(query_str); connection->client->ExecuteStatement(*execStmtRes, *execStmtReq); TFetchResultsReq *fetchReq = new TFetchResultsReq(); fetchReq->__set_operationHandle(execStmtRes->operationHandle); fetchReq->__set_orientation((TFetchOrientation::type)4); TFetchResultsResp *fetchRes = new TFetchResultsResp(); connection->client->FetchResults(*fetchRes, *fetchReq); std::vector vRow = fetchRes->results.rows; cout<<"Row size:" << vRow.size() <https://github.com/apache/hive/tree/trunk/jdbc/src/java/org/apache/hive/jdbc) is Java implementation of thrift client for HS2. thanksPrasad On Tue, Oct 22, 2013 at 7:04 AM, Haroon Muhammad wrote: Thanks Carl and Tejas!!

RE: hive_service.thrift vs TCLIService.thrift
Thanks Vaibhav. Date: Mon, 21 Oct 2013 11:14:28 -0700 Subject: Re: hive_service.thrift vs TCLIService.thrift From: vgumas...@hortonworks.com To: user@hive.apache.org Hi Haroon, hive_service.thrift is the interface definition language (IDL) file for HiveServer (older one), whereas TCLIService.thrift is the IDL for HiveServer2. HiveServer2 was introduced in Hive-0.11.

Hi, Can anyone share what's the difference between hive_service.thrift and TCLIService.thrift? Thanks,
HS2 ODBC incompatibility
Hi, Source under ODBC seems to be incompatible with HS2's changed RPC thrift interface. Are there any plans on getting an updated version out any time sooner ? Thanks,
