How to set up Hive

πŸ€“ Who can do this? You will need your Hadoop administrator to run these commands β€” you may not have access yourself.

Currently, we only support basic username and password authentication for Hive. Complete the following steps to configure it.

Set the right permissions

To configure basic authentication for Hive, enter the following details:

  1. For Host Name, enter the Atlan-accessible Hive instance URL.
  2. For Port, enter the port number where your Hive instance is accessible.
  3. For Default Schema, enter the default schema name in your Hive instance for connection. Atlan will crawl other schemas too β€” not just the default one.

Grant read permission on objects

Grant read permission on objects with the following commands:

GRANT SELECT ON DATABASE <database_name> TO USER <username>;

Atlan requires read permission for all the objects you want to crawl in Hive.

πŸ’ͺ Did you know? Available users and access control may also be controlled or affected by HDFS ACL, LDAP, and any other policy engine that is in effect. Overall, Atlan requires the authenticating user to have read permission at a minimum.
