From the image provided, looks like zk and warden services are running fine. Please run below commands and share the output so we can see which services are not running.

  1. maprcli alarm list
  2. maprcli node cldbmaster
  3. maprcli node list -columns svc 
  4. maprcli node list -columns csvc
  5. maprcli license list -json

Re: HPE Ezmeral Data Fabric Services Problems

These errors are caused by you running the maprcli command on a secure cluster without first generating a valid security ticket.  The error message explains how to resolve this: "Retry after obtaining a new ticket using maprlogin".

The syntax is:

# maprlogin password

Enter your user password when prompted by maprlogin and it should generate a valid security ticket.  After doing so you should be able to run the maprcli commands recommended by Shishir.

Re: HPE Ezmeral Data Fabric Services Problems

you don't need to start/stop the mapr-cldb service manually.  Just make sure the mapr-warden service is running file.  That will make the cldb process up.

Warnder is a wrapper service which keeps an eye on the status of other services running on the nodes which are related to ezmeral data fabric cluster (aka mapr cluster)
