Cloudera Navigator Data Management Overview
Cloudera Navigator Data Management is a
complete solution for data governance, auditing, and related data management
tasks that is fully integrated with the Hadoop platform.
Is Cloudera Navigator a module of Cloudera Manager?
Not exactly. Cloudera Navigator is installed separately, after Cloudera
Manager is installed, and it interacts behind the scenes with Cloudera Manager
to deliver some of its core functionality. Cloudera Manager is used by cluster
administrators to manage the cluster and all its services. Cloudera Navigator
is used by administrators but also by security and governance teams, data
stewards, and others to audit, trace data lineage from source raw data through
form, and perform other comprehensive data governance and stewardship
