[Rdo-list] [heat][autoscaling][cleaning before scale down]

[ICHIBA Sara]

Hey there,

I'm working on the autoscaling of cassandra with heat and ceilometer. I'm
one step away from finishing my template.  Now, I'm looking for a way to
hand a script over to  every cassandra server just before its removal by
heat ( scaledown action). By doing this, I'm sure that the rest of the
cluster won't try anymore to reach that cluster and that the load will be
rebalanced again.

Thank you for your response,
B.regards
Sara
