cdp-doctor ipa status (on FreeIPA Nodes)

Scope

The cdp-doctor ipa status command checks the status and DNS configuration of the FreeIPA server node used by the Cloudera environment for authentication and identity management.

FreeIPA plays a critical role in Kerberos authentication, DNS resolution, and user synchronization across CDP components.

This command helps verify that the FreeIPA node is reachable, correctly configured, and properly integrated with the cluster's DNS zone.

Use Case

  • Validating FreeIPA node setup post-deployment.
  • Troubleshooting Kerberos or authentication errors in the CDP environment.
  • Checking DNS consistency during environment provisioning or upgrades.
  • Ensuring FreeIPA hostname resolution and DNS zone mappings are correct.

Sample Output

Running the cdp-doctor ipa status command displays the following output:

Field Description
type

Identifies the node type (in this case, FREEIPA).

If type is FREEIPA, the command is running on a FreeIPA node.

ip

Displays the IP address assigned to the FreeIPA node.

This value indicates network identity and is used to validate forward and reverse DNS records.

reverse_ip

Reverse lookup IP for DNS validation.

This value indicates network identity and is used to validate forward and reverse DNS records.

fqdn

Fully Qualified Domain Name of the FreeIPA node.

It confirms proper hostname resolution within the environment.

reverse_nslookup

Confirms whether the reverse DNS lookup of the IP resolves to the correct hostname. This value is optional, but should ideally return the FQDN.

If it is blank, the reverse DNS lookup could not be resolved. This could indicate:

  • Incorrect DNS records in FreeIPA or external DNS.
  • Mismatch between hostname and DNS zone configuration.
Misconfigured /etc/hosts entries or PTR records.
dns_zone_match

Indicates whether the node's DNS configuration matches the defined DNS zone used by Cloudera.

An [OK] value indicates that the node's DNS configuration matches the expected Cloudera DNS zone, indicating a healthy status.

A failed value could indicate:

  • Incorrect DNS records in FreeIPA or external DNS.
  • Mismatch between hostname and DNS zone configuration.
Misconfigured /etc/hosts entries or PTR records.
