Let's say I have defined several CreateUsers plugins as follows:
[plugin createAuser]
setup_class = starcluster.plugins.users.CreateUsers
usernames = user_a
[plugin createBuser]
setup_class = starcluster.plugins.users.CreateUsers
usernames = user_b
[plugin createCuser]
setup_class = starcluster.plugins.users.CreateUsers
usernames = user_c
And I define a cluster to run at creation time the createAuser pluging, but
at some later date I would like to add user_b to that same cluster.
I should be able to run the command "starcluster runplugin createBuser
<clustername>" and get user_b propagated into that cluster should I not?
If so, I am not getting the desired behavior.
In fact this mechanism for adding a user evalente after cluster creation
outputs the following:
$ starcluster runplugin create_evalente_user i04dft
StarCluster - (

**************************************************************
I tracked down users.py and found that the self._usernames contains
evalente, but newusers gets a list of existing users back from the
self._get_newusers_batch_file
call.
Has anyone else used the plugin in this manner successfully? What other
ways have people used to achieve user creation post cluster creation?
Thanks,
Eduardo
