HBase Master Alarm

Logged As

NODE_ALARM_SERVICE_HBMASTER_DOWN

Meaning

The HBMaster service on the node has stopped running.

Resolution

To check whether the HBMaster service is running, go to the node information page or the Services page in MCS. Warden will try three times to restart the service automatically. After an interval (30 minutes by default), Warden will again try three times to restart the service. The interval can be configured using the services.retryinterval.time.sec parameter in the warden.conf file. If Warden successfully restarts the HBMaster service, the alarm is cleared. If Warden is unable to restart the HBMaster service, it might be necessary to contact technical support.
