Last updated on MARCH 24, 2020

Applies to:

Big Data Appliance Integrated Software - Version 4.4.0 and later
Linux x86-64


The document details how to enable/disable HDFS Transparent Encryption on Oracle Big Data Appliance (BDA) V4.4.0 and higher using bdacli when the Key Trustee Servers are set up off the BDA.

Carefully review the Cloudera documentation on Managing Encryption Keys and Zones.  Note if you disable HDFS Transparent Encryption you will not be able to access data in encryption zones.

This note is for enabling/disabling HDFS Transparent Encryption for the initial time.  It is not for upgrading an existing implmentation.

Note: This note is based on an example from a BDA V4.4 environment.
