Understanding the Cloudera Manager
architecture
Before we go into installing and using Cloudera Manager, you need to understand the ar-
chitecture of Cloudera Manager and how it functions. Cloudera Manager is composed of
the following two parts:
• Cloudera Manager Server
• Cloudera Manager Agent
The following diagram depicts the Cloudera Manager architecture:
The
Cloudera Manager Server
is the master service that manages the data model of the
entire cluster in a database. The data model contains information regarding the services,
roles, and configurations assigned for each node in the cluster.
The Cloudera Manager Server is responsible for performing the following functions:
• It communicates with Cloudera Manager Agents that are installed on each node of
the cluster and assigns tasks as well as checking the health of each agent by monit-
oring its periodic heartbeats.
• It provides an administrator web interface for the end user to perform administrator
operations.
