Add Alias in config file
Description
When a python script runs, it uses uname()[0] to find the hostname. On guppy, it may return guppy.emg.nysbc.org, which is recorded into the database under apAppionjobData. When we try to check the status of the job from the web, we can't establish a connection.
To work around this I have added an alias to the config file:
$PROCESSING_HOSTS[] = array('host' => 'guppy.scripps.edu',
'alias' => 'guppy.emg.nysbc.org', <----------------------- !!! this is new and optional !!!
'nodesdef' => '2',
'nodesmax' => '16',
etc....
When we look up a host in the config file, if the hostname we are trying to connect to matches the alias name, we will still create the cluster object, using the "host" field as the name.
This needs to be merged to the trunk and 2.2 branch.

Sargis, can you please update all our config files for our 2.2 and trunk installations to include this 'alias' parameter for at least guppy. I'm not sure if other processing hosts have the same issue at this point. Then please assign this back to me so that I can get Daniel to test it.

Thank you Amber. I've added 'alias' => 'guppy.emg.nysbc.org' to config.php on longboard:/srv/www/html/betamyamiweb.
I also checked guppy:/etc/hosts and here is how it looks like:
# Do not remove the following line, or various programs # that require network functionality will fail. 127.0.0.1 localhost.localdomain localhost 10.1.0.1 guppy.emg.nysbc.org guppy 137.131.205.69 guppy.scripps.edu
This might be the reason uname()[0] returns guppy.emg.nysbc.org instead of guppy.scripps.edu.
