Cloudera Impala connection

To access your data in Cloudera Impala, create a connection asset for it.

Cloudera Impala provides SQL queries directly on your Apache Hadoop data stored in HDFS or HBase.

Supported versions

Cloudera Impala 1.3+

Prerequisite for Kerberos authentication

To use Kerberos authentication, the data source must be configured for Kerberos and the service that you plan to use the connection in must support Kerberos. For information, see Enabling platform connections to use Kerberos authentication.

Create a connection to Cloudera Impala

To create the connection asset, you need these connection details:

Database name
Hostname or IP address
Port number
Username and password
SSL certificate (if required by the database server)

For Credentials and Certificates, you can use secrets if a vault is configured for the platform and the service supports vaults. For information, see Using secrets from vaults in connections.

Authentication method

You can choose Kerberos credentials or Username and password.
For Kerberos credentials, you must complete the prerequisite for Kerberos authentication and you need the following connection details:

Service principal name (SPN) that is configured for the data source
User principal name to connect to the Kerberized data source
The keytab file for the user principal name that is used to authenticate to the Key Distribution Center (KDC)
