headless pentaho with hadoop

I'm trying to run pentaho kitchen in a headless server but it seems not to be possible since I need to load big data plugin.
So I inserted in spoon.sh the following in the beggining:
set KETTLE_PLUGIN_PACKAGES=$KETTLE_PLUGIN_PACKAGES,/usr/local/pentaho/data-integration/plugins
export KETTLE_PLUGIN_PACKAGES

Unfortunatly when I do this kitchen and pan will not work in headless server. The following error starts to happen:
Code:

(process:18952): Gtk-WARNING **: Locale not supported by C library.
        Using the fallback 'C' locale.
org.eclipse.swt.SWTError: No more handles [gtk_init_check() failed]

Is there any way to use kitchen and pan without depending on gtk?
This would be usefull to have in an headless server, so clients cloud submit there kjb or ktr files to the server after using kettle in their workstations.

I'm trying to find a way to adapt kjb so <type>HadoopTransJobExecutorPlugin</type> in event could be discarded. This way depedency with plugin could be eliminated and so KETTLE_PLUGIN_PACKAGES doesn't need to be defined.
