I am currently testing auto startup of HDP and HDF clusters using ambari blueprints. My HDP is 2.4.3 (ambari version 22.214.171.124) while HDF is 2.1.4 (ambari version 126.96.36.199). I don't seem to be getting the desired result, as the clusters did not startup on reboot. I've seen submissions saying blueprint only works in the case of a service component crash. In a recent Data Centre failure due to power issues, i believe the service components crashed since it wasn't a graceful stop. I'm wondering why the ambari blueprint didn't work on my clusters. Any one got a clue?
