Ferdy,

I don't think you understand.

What you're asking for doesn't make sense.

Your filters could be built dynamically, so you code it once and based on the 
parameters passed in, you build a filter and apply it to the scan.
Whether you pass in the parameters in a configuration file or from a GUI 
attached to the client code doesn't matter.

Just a clarification ... I've seen some developers do this and its not a good 
practice... You want to avoid putting job specific parameters in a hadoop 
config file.
Use the config file as a way to pass in cloud specific parameters that you want 
to override and use a separate config file to pass in the application specific 
command line options or use command line options.  (I'm sure someone is going 
to argue a counter point to this.)

But getting back to your point. You just need to write some dynamic code for 
your filters and then you can pass in your column list to filter on as a 
parameter.
