@Anurag Mishra 1. Are you running the AMS with proper Heap Settings? (Or with default values) Sometimes due to insufficient heap setting this can happen. Please refer to the following doc to know how to tune the AMS memory settings based on the number of nodes: https://cwiki.apache.org/confluence/display/AMBARI/Configurations+-+Tuning 2. If it still crashes then once you should try to perform the AMS data cleanup and then see if it comes up fine. https://cwiki.apache.org/confluence/display/AMBARI/Cleaning+up+Ambari+Metrics+System+Data 3. Are you running AMS in Embedded Mode (Default) or Distributed Mode (external HBase) ? . ... View more

@uri ben-ari Looks similar another thread describing this kind of behaviour: https://community.hortonworks.com/questions/44942/how-to-updatemodify-a-blueprint-once-the-cluster-i.html . Copying few lines from there: While the Blueprint POST-ed to Ambari will not change as the state of a cluster changes, you can consider "exporting" a Blueprint from a live cluster. After a set of changes to the cluster (Config changes, services added/deleted, etc), exporting the Blueprint will provide a Blueprint that describes the current state of the cluster, which would be different than the original Blueprint used to create the cluster. .
