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:
- 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
