Create an Apache Hive connection

To access your data stored on an Apache Hive database, you will need to know the server and database name that you want to connect to, and you must have access credentials. Once you have created a connection to an Apache Hive database, you can select data from the available tables and then load that data into your app or document.

In Qlik Sense, you connect to an Apache Hive database through the Add data dialog or the Data load editor.

In QlikView you connect to an Apache Hive database through the Edit Script dialog.

Qlik Sense: Apache Hive authentication properties

Authentication properties that can be configured
Property Description Required
Mechanism

Select Single Sign-On, User Name and Password, User Name, or allow connection with No Authentication. Selecting Single Sign-On, User Name and Password, or User Name gives you the option to set up Account properties.

Information noteWhen a connection is created or edited with Single Sign-On selected, the connection uses the credentials of the user who is currently logged into Qlik Sense.

If a user ID is specified for the Delegation UID property, then the connection is tested with the user ID specified in the Delegation UID property and the password for the Delegation UID. Any time the connection properties are changed, the password for the Delegation UID must be reentered to test or save the changes to the connection.

Yes
Kerberos FQDN The fully qualified domain name (FQDN) of the Kerberos authentication server. Yes, when Single Sign-On is selected.
Kerberos Realm The name of the Kerberos realm, which is the set of managed nodes that share the same Kerberos database. Yes, when Single Sign-On is selected.
KrbServiceName The Kerberos service principal name (SPN) of the Apache Hive server. Yes, when Single Sign-On is selected.
SSO user name format

Select the format of the single sign-on (SSO) user name that is used when the name is passed to the Apache Hive server. This setting applies to the SSO user and the Delegation UID.

QlikID (domain\username)

UPN (username@domain.com)

username

Yes, when Single Sign-On is selected.
SSO user name casing

Select the case sensitivity for the single sign-on (SSO) user name that is used when the name is passed to the Apache Hive server. This setting applies to the SSO user and the Delegation UID.

Case sensitive

Upper case

Lower case

Yes, when Single Sign-On is selected.
Delegation UID

The user ID to use for scheduled, automatic reloads. If a Delegation UID is specified, user password is required each time a connection is created or edited, to verify the access to delegation credentials. The ID must be entered in the format domain\username.

Information noteManual reloads always use the ID of the user who is logged into Qlik Sense, not the Delegation UID.

No, but the ID can be provided when Single Sign-On is selected.

Information noteBecause scheduled reloads are performed under a system account instead of a real user, Single Sign-On may not be necessary. The scheduled reloads can be performed using predefined NTLM authentication.
User name User name for the Apache Hive connection. Yes, when User Name and Password or User Name is selected.
Password

Password for the Apache Hive connection.

Information noteWhen Single Sign-On is selected, the password is for the user identified with the Delegation UID property. If a user is not specified in the Delegation UID property, then the Password property must be left blank for single sign-on (SSO).
Yes, when User Name and Password is selected.
Name Name of the Apache Hive connection. The default name will be used if you do not enter a name. Yes

QlikView: Apache Hive authentication properties

Account properties

Credentials

Credentials are used to prove that a user is allowed to access the data in a connection.

There are two types of credentials that can be used when making a connection in Qlik Sense SaaS. If you leave the User defined credentials check box deselected, then only one set of credentials will be used for the connection. These credentials belong to the connection and will be used by anyone who can access it. For example, if the connection is in a shared space, every user in the space will be able to use these credentials. This one-to-one mapping is the default setting.

If you select User defined credentials, then every user who wants to access this connection will need to input their own credentials before selecting tables or loading data. These credentials belong to a user, not a connection. User defined credentials can be saved and used in multiple connections of the same connector type.

In the Data load editor, you can click the Primary key underneath the connection to edit your credentials. In the hub or Data manager, you can edit credentials by right-clicking on the connection and selecting Edit Credentials.

Account properties that can be configured
Account property Description
User defined credentials Select this check box if you want users that access this connection to have to input their own credentials. Deselect this check box if credentials can be shared with anyone who has access to this connection.
