## Minimum user permissions In order to bring your Hive data into Data Quality & Observability (self-hosted), you need the following permissions. * The Kerberos user has read permissions on Hive tables. * ROLE\_ADMIN assigned to your user in Collibra DQ. ## Recommended and required connection properties | Required | Connection Property | Type | Value | | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------------- | ------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | Yes | Name | Text | The unique name of your connection. Ensure that there are no spaces in your connection name. | | No | Is Hive | Option | Uses the Hive server engine for distributed speed and scale. This option sets `hiveNative` options for Spark Jobs. | | Yes | Connection URL | String |

The connection string path of your Hive connection.

When referring to the example below, replace the ${value} sections of the connection URL with your actual value.

jdbc:hive2://${host}:10000/default;AuthMech=1;KrbHostFQDN=\_HOST;KrbServiceName=hive;SSL=1;AllowSelfSignedCerts=1

| | Yes | Driver Name | String |

The driver class name of your connection.

com.cloudera.hive.jdbc.HS2Driver

| | Yes | Port | Integer |

The port number to establish a connection to the datasource.

The default port is 10000

| | No | Limit Schemas | Option |

Allows you to manage usage and restrict visibility to only the necessary schemas in the Explorer tree.

See Limiting schemas to learn how to limit schemas from the Connection Management page.

When you include a restricted schema in the query of a DQ Job, the query scope may be overwritten when the job runs. While only the schemas you selected when you set up the connection are shown in the Explorer menu, users are not restricted from running SQL queries on any schema from the data source.

| | No | Source Name | String | N/A | | No | Target Agent | Option | The [Agent](/data-quality-self-hosted/installation/agent.md) that submits your Spark job for processing. | | Yes | Auth Type | Option |

The method to authenticate your connection.

The configuration requirements are different depending on the Auth Type you select. See Authentication for more details on available authentication types.

| | No | Properties | String |

The configurable driver properties for your connection. Multiple properties must be semicolon-delimited, and each property=value pair, including the last one, must end with a semicolon (;). abc=123;test=true;

Optionally add the following driver property to remove the enforcement of unique column names:

hive.resultset.use.unique.column.names=false

Optionally add the following driver properties to set the Spark conf spark.hadoop.hive.metastore.uris and allow Spark to read through a warehouse catalog, such as Hive:

dq.storage.cxn=${connection-name},dq.metastore.host=${hostname},dq.metastore.port=9083

| ## Authentication Select an authentication type from the dropdown menu. The options available in the dropdown menu are the currently supported authentication types for this data source. {% tabs %} {% tab title="Kerberos Password Manager" %} | Required | Field | Description | | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | Yes | Principal | The Kerberos entity to authenticate and grant access to your connection. | | Yes | Script |

The file path that contains the script file used to interact with and authenticate a Kerberos user.

:glasses-round: Example: /tmp/keytab/hive\_pwd\_mgr.sh

| | No | Param $1 | Optional. Additional Kerberos parameter. | | No | Param $2 | Optional. Additional Kerberos parameter. | | No | Param $3 | Optional. Additional Kerberos parameter. | | {% endtab %} | | | {% tab title="Kerberos Keytab" %} | Required | Field | Description | | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | Yes | Principal | The Kerberos entity to authenticate and grant access to your connection. | | Yes | Keytab |

The file path of the keytab file that contains the encrypted key for a Kerberos principal.

:glasses-round: Example: /tmp/keytab/hive\_user.keytab

| | {% endtab %} | | | {% tab title="Kerberos Password" %} | Required | Field | Description | | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------- | ------------------------------------------------------------------------ | | Yes | Principal | The Kerberos entity to authenticate and grant access to your connection. | | Yes | Password | The secret credential associated with your Kerberos principal. | | {% endtab %} | | | {% tab title="Password TGT Cache" %} | Required | Field | Description | | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------- | ------------------------------------------------------------------------------------- | | Yes | Principal | The Kerberos entity to authenticate and grant access to your connection. | | Yes | TGT Cache | The ticket-granting ticket cache that stores the TGT to authenticate your connection. | | {% endtab %} | | | | {% endtabs %} | | | ## Known limitations * When a column starts with a number, special character, or space, you may need to wrap the column name in square brackets `[ ]`, to prevent column names from being stripped.
