Seungun Choe resolved TAJO-1264.
--------------------------------
Resolution: Won't Fix
Tajo client for server is used REST server instead of thrift server.
> C/C++ Client
> ------------

> Key: TAJO-1264
> URL: https://issues.apache.org/jira/browse/TAJO-1264
> Project: Tajo
> Issue Type: New Feature
> Reporter: Hyoungjun Kim
> Assignee: Seungun Choe
>
> Currently Tajo is support only Java client. I think supporting multiple
> language is important for growing Tajo community. TAJO-1206 makes it easier
> to support multiple languages.
> This issue is for implementing C/C++ client which calls to TajoThriftServer.
> Tajo C/C++ client may have Java Tajo Client's method like the following.
> {code}
> // Connection API
> TajoThriftConnection* OpenConnection(const char* database, std::string host,
> int port, char* err, size_t err_len);
> // Database API
> TajoReturn CloseConnection(TajoThriftConnection* conn, char* err, size_t
> err_len);
> TajoReturn CreateDatabase(TajoThriftConnection* conn, const char*
> database_name, char* err, size_t err_len);

> TajoReturn DropDatabase(TajoThriftConnection* conn, const char*
