Mapping Impersonation User Name

Mapping Impersonation User Name

A mapping impersonation user name is valid for the native and Hadoop execution environment. Use mapping impersonation to impersonate the Data Integration Service user that connects to Hive, HBase, or HDFS sources and targets that use Kerberos authentication.
Enter a user name in the following format:
<Hadoop service name>/<hostname>@<YOUR-REALM>
Where:
  • Hadoop service name is the name of the Hadoop service that the Hive, HBase, or HDFS source or target resides.
  • Host name is the name or IP address of the Hadoop service.
  • YOUR-REALM is the Kerberos realm.
You can only use the following special characters as delimiters: '/' and '@'
