What is the issue

[#2 · Accepted solution]

I fixed the issue, by doing below

Seems Level Database DB is corrupted, and did below

mv /var/lib/cloudera-service-monitor /var/lib/cloudera-service-monitor.moved

mv /var/lib/cloudera-host-monitor /var/lib/cloudera-host-monitor.moved

Then restarted the services again, it worked
