Getting Started with Apache Hive

There are two main ways of integration Apache Hive to Secoda.

  1. Direct connection to Apache Hive

  2. Using MySQL metastore

Direct Connection to Hive

1. Create Role for Secoda

To ensure controlled access, we'll begin by creating a dedicated role for Secoda in Hive:

-- Create a new role for Secoda
CREATE ROLE SECODA;

-- Grant read permissions on database
GRANT SELECT ON DATABASE <database_name>.* TO ROLE SECODA;

2. Create User for Secoda

Creating a user in Hive will depend on the underlying authentication and user management system in place (like LDAP, Kerberos, etc.). Typically, a Hive admin would create users outside of Hive. Once they exist, you can grant roles to them within Hive:

-- Grant the role to user
GRANT ROLE SECODA TO USER SECODA_USER;

3. Connect Hive to Secoda

To integrate Secoda with your Hive setup:

  • In the Secoda App, select Add Integration on the Integrations page.

  • Search for and select "Hive".

  • Provide the necessary credentials:

    • User: The username (as created above).

    • Password: The password for the user.

    • Host: Hive Server2 host.

    • Port: This is usually 10000 but might vary based on your specific setup.

4. Security: Whitelisting IPs

The process of whitelisting IPs would be external to Hive. It typically occurs at the level of Hive Server2 or in the underlying infrastructure, such as firewalls or security groups if you're using a cloud platform. Ensure that you add the Secoda IP address to the list of allowed IPs.

MySQL Metastore Connection

1. Connect Metastore to Secoda

To integrate Secoda with your Hive setup:

  • In the Secoda App, select Add Integration on the Integrations page.

  • Search for and select "Hive".

  • Provide the necessary credentials:

    • User: The username for your MySQL user

    • Password: The password for the user.

    • Host: MySQL server host.

    • Port: This is usually 3306 but could be different

    • Database: This is the database for your MySQL metastore

      • Please ensure the user has select access to this database

2. Security: Whitelisting IPs

Ensure that you add the Secoda IP address to the list of allowed IPs on your MySQL server.
