Note

These instructions are for the hive Hive ODBC driver available in Hive for HiveServer1.
There is no ODBC driver available for HiveServer2 as part of Apache Hive. There are third party ODBC drivers available from different vendors, and most of them seem to be free.

...

The following software components are needed for the successful compilation and operation of the Hive ODBC driver:

  • Hive Server - – a service through which clients may remotely issue Hive commands and requests. The Hive ODBC driver depends on Hive Server to perform the core set of database interactions. Hive Server is built as part of the Hive build process. More information regarding Hive Server usage can be found here.
  • Apache Thrift - – a scalable cross-language software framework that enables the Hive ODBC driver (specifically the Hive client) to communicate with the Hive Server. See this link for the details on Thrift Installation. The Hive ODBC driver was developed with Thrift trunk version r790732, but the latest revision should also be fine. Make sure you note the Thrift install path during the Thrift build process as this information will be needed during the Hive client build process. The Thrift install path will be referred to as THRIFT_HOME.

...

Internally, the Hive ODBC Driver contains two separate components: Hive client, and the unixODBC API wrapper.

  • Hive client - – provides a set of C-compatible library functions to interact with Hive Server in a pattern similar to those dictated by the ODBC specification. However, Hive client was designed to be independent of unixODBC or any ODBC specific headers, allowing it to be used in any number of generic cases beyond ODBC.
  • unixODBC API wrapper - – provides a layer on top of Hive client that directly implements the ODBC API standard. The unixODBC API wrapper will be compiled into a shared object library, which will be the final form of the Hive ODBC driver. The wrapper files will remain a file attachment on the associated JIRA until it can be checked into the unixODBC code repository: HIVE-187, HIVE-1101.
