We do not have an option to force delete a cluster. Just so that I
understand ­ did you mean when all services become 'INSTALLED' from
'STARTED' (that is after all services have stopped).

Hi Sumit,

I'm using 1.2.4...  I noticed that if I wait for all services to become
'INSTALLED' then I can delete the cluster.

Do you know if there's a way to avoid this step and forcibly delete the
cluster?  Or do I need to update?

Cheers,
Christian
