Hello 

 

We are receiving alerts from the cluster saying that httpfs is DOWN. Can you let me know w

Automated alert for the cluster:

Alarm raised: NODE_ALARM_SERVICE_HTTPFS_DOWN:hostname:NODE_ALARM

Can not determine if service: httpfs is running. Check logs at: /opt/mapr/httpfs/httpfs-1.0/logs
