interactive analytics and business intelligence. Its highly optimized
architecture makes it ideally suited for traditional BI-style queries with
joins, aggregations, and subqueries. It can query Hadoop data files from a
variety of sources, including those produced by MapReduce jobs or loaded
into Hive les. The YARN resource management component lets Impala
coexist on clusters running batch workloads concurrently with Impala SQL
queries. You can manage Impala alongside other Hadoop components through
the Cloudera Manager user interface, and secure its data through the
Sentry authorization framework.
Search—Provides near real-time access to data stored in or ingested
into Hadoop and . Search provides near real-time indexing, batch
indexing, full-text exploration and navigated drill-down, as well as a
simple, full-text interface that requires no SQL or programming skills.
Fully integrated in the data-processing platform, Search uses the
flexible, scalable, and robust storage system included with CDH. This
eli tes the need to move large data sets across infra ures to
perform business t s.
Manager—A sophisti ed application used to deploy, manage, monitor,
and diagnose issues with your CDH deployments. Cloudera Manager provides
the Admin Console, a -based user interface that makes administration of
your enterprise data simple and straightforward. It also includes the
Cloudera Manager , which you can use to obtain cluster health information
and metrics, as well as configure Cloudera Manager.
Navigator—End-to-end data management and security for the CDH
platform. Cloudera Navigator Data Management enables administrators, data
managers, and analysts explore vast data collections in Hadoop. Cloudera

s. The robust auditing, data management, lineage management, lifecycle
management, and encryption key management in Cloudera Navigator allow
enterprises to adhere to stringent compliance and regulatory requirements.

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
如果不涉及到Cloudera Navigator可以不用安装。 审计等方面，
