Implementing CTE on HDFS

This section describes how to implement CTE protection on your HDFS NameNode or DataNode. If you enable HDFS data replication, protecting one node at a time allows you to maintain the HDFS cluster. When all of the nodes are configured, you can create GuardPoints on specific HDFS files and directories.

These instructions require that the HDFS Administrator and Administrator work in tandem to complete separate tasks.

Note

The instructions below assume that each NameNode and DataNode exist on their own separate host. If you have a NameNode and DataNode on the same host, see Implementing CTE on HDFS on a Single Host.

CTE on HDFS Implementation Assumptions

• You have installed, configured and registered CTE on all of the NameNodes and DataNodes in the Hadoop cluster.

• The HDFS Administrator has knowledge and experience with HDFS and Ambari.

• The CipherTrust Manager Administrator has knowledge and experience with CTE.

• The two can work and communicate in tandem with each other.
