> When HTTP is used as the transport mode by the Hive JDBC driver, we noticed that there is an additional open/close session just to validate the connection.
>
> TCLIService.Iface client = new TCLIService.Client(new TBinaryProtocol(transport));
> TOpenSessionResp openResp = client.OpenSession(new TOpenSessionReq());
> if (openResp != null) {
> client.CloseSession(new TCloseSessionReq(openResp.getSessionHandle()));
> }
>
> The open session call is a costly one and should not be used to test transport.
