If the Hadoop cluster uses Kerberos authentication or SSL/TLS, you must configure the Informatica domain to access the cluster. If the cluster uses transparent encryption, you must configure the Key Management Server (KMS) for Informatica user access.
Depending on the security implementation on the cluster, you must perform the following tasks:
Cluster uses Kerberos authentication.
You must configure the Kerberos configuration file on the Data Integration Service machine to match the Kerberos realm properties of the Hadoop cluster. Verify that the Hadoop Kerberos properties are configured in the Data Integration Service and the Metadata Access Service.
If the cluster uses Kerberos and does not use the Enterprise Security Package, you can configure Ranger authorization separately to grant permissions to Informatica users.
