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

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 
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.
See which authentication type applies on each connector's page.
