Name Node Health Bad

New Contributor

In Cloudera Manager., I could always see this Alert in health Tests Section -


NameNode summary: (Availability: Unknown, Health: Good), (Availability: Unknown, Health: Good). This health test is bad because the Service Monitor did not find an active NameNode.


I do not see any service Disruption and both the servers are up and running. Looking for help what need to be checked and why this heath test alert is persistent.

This indicates that the host monitor service is not getting information from the Namenode roles.

Please try resolving the issue by restarting cm agents on the name node host.
