Introducing Cloudera Manager
Cloudera Manager is a web-browser-based administration tool to manage Apache Hadoop
clusters. It is the centralized command center to operate the entire cluster from a single in-
terface. Using Cloudera Manager, the administrator gets visibility for each and every com-
ponent in the cluster.
A few of the important features of Cloudera Manager are listed as follows:
• It provides an easy-to-use web interface to install and upgrade CDH across the
cluster.
• Each node in the cluster can be assigned roles and can be configured accordingly.
It allows the starting and stopping of services across all nodes from a single web
interface.
• It provides complete information for each node, for example, CPU, memory disk,
and network statuses.
Cloudera Manager is available in the following two editions:
• Cloudera Manager Standard (free)
• Cloudera Manager Enterprise (licensed)
Cloudera Manager Standard Edition, though free, is a feature packed tool that can be used
to deploy and manage Apache Hadoop clusters with no limitation on the number of nodes.
However, there are a few features that are not part of the standard edition. These are as fol-
lows:
•
Lightweight Directory Access Protocol
(
LDAP
) authentication
• Alerts via
SNMP
(
Simple Network Management Protocol
)
• Operational reports and support integration
• Enhanced cluster statistics
• Disk quota management
These features and a few more are part of the enterprise edition. To get the Cloudera Man-
ager Enterprise Edition, you need to purchase a license. However, as of now, you can try
the Enterprise Edition free for 60 days.
