To access your data in Apache Impala, create a connection asset for it.
Apache Impala provides high-performance, low-latency SQL queries on data that is stored in popular Apache Hadoop file formats.

Create a connection to Apache Impala
To create the connection asset, you need these connection details:
- Database (optional): If you do not enter a database name, you must enter the catalog name, schema name, and the table name in the properties for SQL queries.
- Hostname or IP address
- Port number
- Username and password
- SSL certificate (if required by the database server)
Authentication method
Select the security mechanism to use to authenticate the user:
-
Username and password or Kerberos credentials
Available Kerberos selections depend on whether you select Personal or Shared credentials. -
LDAP
Use an LDAP security mechanism for external authentication.Note:SPSS Modeler supports only the Username and password authentication method.
For Private connectivity, to connect to a database that is not externalized to the internet (for example, behind a firewall), you must set up a secure connection.
