Cloudera Navigator 2 Frequently Asked Questions
Is Cloudera Navigator a module of Cloudera Manager?
- Data Management - Data management provides visibility into and control over the data residing in Hadoop datastores and the computations performed on that
data. The Cloudera Navigator features that address the data management needs of Hadoop administrators, data stewards, and data scientists are:
- Auditing data access and verifying access privileges - The goal of auditing is to capture a complete and immutable record of all activity within a system. Cloudera Navigator auditing features add secured, real-time audit components to key data and access frameworks. Cloudera Navigator allows compliance groups to configure, collect, and view audit events, and to understand who accessed what data and how.
- Searching metadata and visualizing lineage - Cloudera Navigator metadata management features allow DBAs, data stewards, business analysts, and data scientists to define, search for, amend the properties of, and tag data entities and view relationships between datasets.
- Policies - Cloudera Navigator policy features enable data stewards to specify automated actions based on data access or on a schedule to add metadata, create alerts, and move or purge data.
- Analytics - Cloudera Navigator analytics features enable Hadoop administrators to examine data usage patterns and create policies based on those patterns.
- Data Encryption - Data encryption and key management provide a critical layer of protection against potential threats by malicious actors on the network
or in the datacenter. Encryption and key management are also requirements for meeting key compliance initiatives and ensuring the integrity of your enterprise data. The following Cloudera Navigator
components enable compliance groups to manage encryption:
- Cloudera Navigator Encrypt transparently encrypts and secures data at rest without requiring changes to your applications and ensures there is minimal performance lag in the encryption or decryption process.
- Cloudera Navigator Key Trustee Server is an enterprise-grade virtual safe-deposit box that stores and manages cryptographic keys and other security artifacts.
- Cloudera Navigator Key HSM allows Cloudera Navigator Key Trustee Server to seamlessly integrate with a hardware security module (HSM).
The Cloudera Navigator data management component is implemented as two roles in the Cloudera Management Service: Navigator Audit Server and Navigator Metadata Server. You can add Cloudera Navigator data management roles while installing Cloudera Manager for the first time or into an existing Cloudera Manager installation. For information on compatible Cloudera Navigator and Cloudera Manager versions, see the Product Compatibility Matrix for Cloudera Navigator product compatibility matrix.

Is Cloudera Navigator included with a Cloudera Enterprise Enterprise Data Hub Edition license?
Yes. Cloudera Navigator is included with Cloudera Enterprise Enterprise Data Hub Edition license and can be selected as a choice with a Cloudera Enterprise Flex Edition license.
Can Cloudera Navigator be purchased standalone, that is, without Cloudera Manager?
Cloudera Navigator components are managed by Cloudera Manager. Therefore, Cloudera Manager is a prerequisite for Cloudera Navigator.
What Cloudera Manager, CDH, and Impala releases does Cloudera Navigator 2 work with?
See Cloudera Navigator 2 Requirements and Supported Versions.
Is Cloudera Navigator open source or closed source?
Cloudera Navigator is a closed-source management tool that adds to the Cloudera suite of management capabilities for Hadoop.
How are Cloudera Navigator logs different from Cloudera Manager logs?
Cloudera Navigator tracks and aggregates only the accesses to the data stored in CDH services and used for audit reports and analysis. Cloudera Manager monitors and logs all the activity performed by CDH services that helps administrators maintain the health of the cluster. The target audiences of these logs are different but together they provide better visibility into both the data access and system activity for an enterprise cluster.
