I have a lot of issues on ambari hosts , is it possible to recreate a cluster? or recreate its hosts?
Everything is doable, but you need to give more details than just having problems with ambari host(s)? What is your Ambari/HDP/HDF versions? OS and exactly what issues are you experiencing it a dev cluster of prod? Was it working before if so what changes did you make that triggers these issues?.
It would be a good idea to share logs especially of your Ambari server etc.
Once you attach that information I am sure members will be willing to help you out.
