Subject How to propagate property changes ?
Date Tue, 10 Mar 2015 23:08:53 GMT
I wonder what is the best way to propagate property changes other than to
restart the service ?

Let's say we want to change a few properties in *-site.xml for the service,
and need these properties to be updated in the files on the actual nodes.
Then, we would like to perform some upgrade steps and only then start the
service. Starting the service just to pick up changed properties is not
ideal as the service start will fail as it has not yet been upgraded.

We are using Ambari 1.7.0.
