Starburst Elasticsearch connector

The Starburst Elasticsearch connector is an extended, tested and fully supported version of the Elasticsearch connector with configuration and usage identical.

The following improvements are included:

Requirements

• Fulfill the Elasticsearch connector requirements.

• Additional features of the connector require a valid Starburst Enterprise license, unless otherwise noted.

Security

The connector includes the following security-related feature.

Kerberos authentication

The connector supports Kerberos authentication using a keytab.

To configure Kerberos authentication with a keytab, add the following catalog configuration properties to the catalog properties file:

elasticsearch.security=KERBEROS
kerberos.client.principal=example@example.com
kerberos.client.keytab=etc/kerberos/example.keytab
kerberos.config=etc/kerberos/krb5.conf

With this configuration the user example@example.com, defined in the principal property, is used to connect to the database, and the related Kerberos service ticket is located in the example.keytab file.
