Metadata Access Service

Metadata Access Service

After you upgrade, you can create a Metadata Access Service for
Data Engineering Integration
.
The Metadata Access Service is an application service that allows the Developer tool to access Hadoop connection information to import and preview metadata.
The Metadata Access Service contains information about the Service Principal Name (SPN) and keytab information if the Hadoop cluster uses Kerberos authentication.
The Metadata Access Service is not dependent on other services. You can create a Metadata Access Service in any order. When you import an object from a Hadoop cluster, the HBase, the Hive, and the HDFS connections use Metadata Access Service to extract the object metadata at design time.
