> Right now each role can define event handlers for bootstrap and configure. I suggest
that the Whirr core should be aware of more service lifecycle events like: start, stop &
cleanup. This semantic improvement should allow us to add more features like: cluster reconfiguration
(e.g. update Hadoop settings and restart all the nodes - rolling restart), add / remove nodes
etc.
