@Jay SenSharma So the thing is, that we are trying to see if something is possible, by using Ambari. What we want to do is add extra nodes to a cluster whenever it gets overloaded beyond a certain point, and whenever the load goes to normal, we would like to remove the said extra nodes. As such we would ideally like to know via an email alert if the CPU/Memory of the datanodes are over a certain amount so that we can add the extra nodes in at the point. Is this possible, or even atleast approachable using Ambari?
