Host Inspector

You can use the host inspector to gather information about hosts that Cloudera Manager is currently managing.

You can review this information to better understand system status and troubleshoot any existing issues. For example, you might use this information to investigate potential DNS misconfiguration.

The inspector runs tests to gather information for functional areas including:

Networking
System time
User and group configuration
HDFS settings
Component versions

Common cases in which this information is useful include:

Installing components
Upgrading components
Adding hosts to a cluster
Removing hosts from a cluster
