Big Data Management can use LDAP authentication to access Hive metadata and preview Hive data. To run mappings, Informatica recommends setting the impersonation user or the operating system profile user name as the Hive connection user name.

Big Data Management can use LDAP authentication to access Hive metadata. However, Kerberos authentication takes precedence when you run Big Data Management mappings because the mappings can contain Hive, HDFS, or any other sources and targets.

In a Hortonworks HDP environment that uses Kerberos authentication, Informatica does not recommend LDAP to authenticate Hive.
