HPE Ezmeral Data Fabric (MapR) Keycloak Service Degraded

[SunnyC]

We are installing a new 5-node cluster of HPE Ezmeral Data Fabric (MapR) on RHEL 8.8. We are using Core 7.7.0 and EEP 9.2.2.

We are facing difficulty solving the NODE_ALARM_SERVICE_KEYCLOAK_DOWN alarm in MCS with other error.

After I change the default port from 8080 to 8081 in the keycloak.conf file, I rerun configure.sh with the keycloak flag but it still failed.

Keycloak service log only shows the service is trying to start as below.

 

Below is a sample log when keycloak is manually executed with root account:

We also find the fuser mount point constantly in ? state after i configure the keycloak with confiure.sh

The service failure don't have direct impact to our regular operation but it may trigger some security concern. Is the fusermount causing the error? Or is it possible to remove the keycloak service without great impact to the server?

Dear @AwezS ,

We are doing installation with installer 1.18. We don't have access to LDAP server at this point so I believe keycloak service is not necessary needed in our setup.

Sunny

HI Sunny,

If you are not going to use the Keycloak service you can just remove the package to get this solved.

Do I need to use the installer to update the topology? Or I can just yum erase it and run the configure.sh?
