Cloudera Navigator 2 Frequently Asked Questions

Cloudera Navigator and Cloudera Manager complement each other. Cloudera Manager helps you manage services and Cloudera Navigator helps you manage the data stored in those services. Cloudera Navigator provides the following components:

• Data Management - Provides visibility into and control over the data in Hadoop datastores, and the computations performed on that data. Hadoop administrators, data stewards, and data scientists can use Cloudera Navigator to:
  • Get an "at-a-glance" overview of cluster activity - Use the Data Stewardship dashboard to get a high-level view of the state of the data and data usage on the cluster. The dashboard displays information about table, file, and database activity, table and file creation and modification trends, operations, and other information captured by the Navigator Metadata Server.
  • Audit data access and verify access privileges - The goal of auditing is to capture a complete and immutable record of all activity within a system. Cloudera Navigator auditing adds secure, real-time audit components to key data and access frameworks. Compliance groups can use Cloudera Navigator to configure, collect, and view audit events that show who accessed data, and how.
  • Search metadata and visualize lineage - Cloudera Navigator metadata management allows 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 - Data stewards can use Cloudera Navigator policies to define automated actions, based on data access or on a schedule, to add metadata, create alerts, and move or purge data.
  • Analytics - Hadoop administrators can use Cloudera Navigator analytics 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).
