Description of problem:
I've noticed that sometimes a change in a puppet class on the satellite server is not immediately visible to a client.

I'm currently working on developing some puppet modules so I've created a custom environment on the satellite (/etc/puppet/environments/testing) where I have my git checkout.

 Whenever I do a change in one of the classes, I run 

hammer proxy import-classes --name <my_satellite> --environment testing
 
And then on the client, I run "puppet agent -td" to see what happens

I've noticed however that sometimes, the changes are not seen by the client on the first run, rather what is executed is the old class without the changes is being executed. Highly annoying.

Is there something I'm missing, some part of the importing to the puppet master that happens in the background? And if so, is there a way of finding out if it's done?

Various suggestions I've received is to delete /var/lib/puppet/client_data/* on the client, though to my understanding puppet agent --test should ignore cache.

Another suggestions is to restart the puppet master on the satellite server (httpd).

Ideally, I would like hammer not to return before everything really was finished so to speak.

Version-Release number of selected component (if applicable):
