Hi @Jay Kumar SenSharma, The log file doesn't show any warning or error on saving. it even says save successful in UI. The log is attached for reference. What i noticed is that in case of HDP service from HDP 2.6 stack, there is a HTTP PUT call happening on saving configs which then pushes it to stale state to the API : /api/v1/clusters/dev after a call to /api/v1/stacks/HDP/versions/2.6/validations But for my stack service, the same doesn't get called. Only validation call happens. I exported the PUT from HDP Stack as a curl bash command, modified it for my stack and service with proper config params as the data and ran the curl from the shell. This triggered the change to happen and UI showed stale configs. So what is causing the config push to not happen from the UI?ambari-server.txt ... View more
