Apache Hive

This is the implementation of the Hive data handler for MindsDB.

Apache Hive is a data warehouse software project built on top of Apache Hadoop for providing data query and analysis. Hive gives an SQL-like interface to query data stored in various databases and file systems that integrate with Hadoop.

​

Implementation

This handler is implemented using the pyHive, a Python library that allows you to use Python code to run SQL commands on Hive.

The required arguments to establish a connection are as follows:

• user is the username associated with the database.
• password is the password to authenticate your access.
• host is the server IP address or hostname.
• port is the port through which TCP/IP connection is to be made.
• database is the database name to be connected.
• auth defaults to CUSTOM if not provided. Check for other options in here.

​

Usage

In order to make use of this handler and connect to the Hive database in MindsDB, the following syntax can be used:

CREATE DATABASE hive_datasource
WITH
  engine = 'hive',
  parameters = {
    "user": "demo_user",
    "password": "demo_password",
    "host": "127.0.0.1",
    "port": "10000",
    "database": "default"
  };

You can use this established connection to query your table as follows:

SELECT *
FROM hive_datasource.table_name;
