Create an Apache Drill connection

To access your data in an Apache Drill data store, you will need to know the Drill server you want to connect through. Once you have created a connection to an Apache Drill data store, 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 Drill database through the Add data dialog or the Data load editor.

Authenticating the driver

Qlik Sense: Apache Drill authentication properties

Authentication properties that can be configured
Property Description Required
Authentication Type

Specifies how the driver authenticates the connection to Drill,by choosing No Authentication or Plain.
Plain is basic authentication that uses a user name and a password from Drill. Selecting Plain gives you the option to set up Account properties.

Username The user name that you use to access the Drill server. Yes, if Authentication Type is set to Plain.
Password The password corresponding to the Username. Yes, if Authentication Type is set to Plain.

Name of the Apache Drill connection.

No, the default name will be used if you do not enter a name.

Account properties


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.
New credentials Drop-down menu item that appears if User defined credentials is selected.

Property Description Required
Max String Length

Maximum length of string fields. This can be set from 256 to 16384 characters. The default value is 4096.
