> The scenario is as following:

> I was trying to deploy hadoop cluster with heat Auto Scaling template. 
> 
> When scale up a slave node, I can use user-data to do some post work for configuration file on hadoop master node base on the information of slave node (The mainly configuration file is conf/slaves as I need to put slave node to this file);
> 
> But when scale down, seems I have no chance to do some configuration for the master node (Remove the scale down node from conf/slaves) as master node do not know which slave node was scale down.
