Fine Grained Authorization
When you select the option to observe fine grained authorization in a Hive source, the mapping observes the following:
If you do not select the option, the Blaze and Spark engines ignore the restrictions and masking rules, and results include restricted or sensitive data.
LDAP user name of the user that the Data Integration Service impersonates to run mappings on a Hadoop cluster. The user name depends on the JDBC connection string that you specify in the Metadata Connection String or Data Access Connection String for the native environment.
If the Hadoop cluster uses Kerberos authentication, the principal name for the JDBC connection string and the user name must be the same. Otherwise, the user name depends on the behavior of the JDBC driver. With Hive JDBC driver, you can specify a user name in many ways and the user name can become a part of the JDBC URL.
If the Hadoop cluster does not use Kerberos authentication, the user name depends on the behavior of the JDBC driver.
If you do not specify a user name, the Hadoop cluster authenticates jobs based on the following criteria:
