There are 3 major components in Hive as shown in the architecture diagram. They are hive clients, hive services and Meta Store. Under hive client, we can have different ways to connect to HIVE SERVER in hive services.
These are Thrift client, ODBC driver and JDBC driver. Coming to thrift client, it provides an easy environment to execute the hive commands from a vast range of programming languages. Thrift client bindings for Hive are available for C++, Java, PHP scripts, python scripts and Ruby. Similarly, JDBC and ODBC drivers can be used for communication between hive client and hive servers for compatible options.
