Database Reference
In-Depth Information
• It calculates and displays dashboards of the health for the entire cluster.
• It monitors the important parameters such as disk usage, CPU, and RAM for each
node in the cluster. It also allows full control on the Hadoop daemons running on
the cluster.
• It manages the Kerberos credentials for the services running on the cluster. Ker-
beros is the tool used to manage the authentication and authorization requirements
of the cluster.
• It exposes a set of easy-to-use APIs that helps developers write their own applica-
tions to interact with the Cloudera Manager Server.
The Cloudera Manager Agent is installed on each node of the cluster. It is responsible for
accepting tasks from the Cloudera Manager Server and performs the starting and stopping
of Hadoop daemons on its own node. It is also responsible for gathering all system-level
information and statistics and is relayed back to the Cloudera Manager Server.
All communication between the server and its agents is done over HTTP(S). The user also
connects to the server using a web browser via HTTP(S). The user uses the web applica-
tion to perform all the administrator operations.
