I'm having a real trouble getting hiera to work as expected.

My current setup has a puppet master and an agent.  On both I have the same 
/etc/hiera.yaml file linked into the /etc/puppet directory.  I've also been 
able to confirm that hiera is seeing the right json files in /var/lib/hiera.

What I'm seeing right now is that if I hard code a value (in my case a 
value called "role_puptest1").  In the class I'm working on, if I hardcode 
that value into the hiera lookup:

    $server_role = hiera('role_puptest1')

then puppet  agent runs just fine.  However, if I build the value 
"role_puptest1" from other information, for instance like this:

   $role_value = prefix([$hostname],'role_')
   $server_role = hiera($role_value)

I get this error when running the puppet agent:

Error: Could not retrieve catalog from remote server: Error 400 on SERVER: 
Could not find data item role_puptest1 in any Hiera data file and no 
default supplied at 
/etc/puppet/modules/server/iptables2/manifests/init.pp:9 on node 
puptest1.library.nd.edu

Based on the error, it is parsing the role_value properly (still has 
"role_puptest1"), but it is not finding the value in the file.  At the same 
time, command line hiera on both my agent and my master find the file 
properly:

puptest1 800$ hiera role_puptest1
role_LOCKSS

So, why is the generated value which comes up with the same string of data 
not finding the record in the hiera data file?

I'm using hiera 1.2.1 and puppet 3.2.4 on RHEL 6.

Thanks,
Tom
