Configure Access to Secure Hadoop Clusters

Configure Access to Secure Hadoop Clusters

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.
Cluster uses SSL/TLS.
You must import security certificates to the Data Integration Service and the Metadata Access Service machines.
Cluster uses transparent encryption.
If the transparent encryption uses Cloudera Java KMS, Cloudera Navigator KMS, or Apache Ranger KMS, you must configure the KMS for Informatica user access.

Informatica Big Data Management Administrator Guide
