Jerome Boulon commented on CHUKWA-473:
--------------------------------------

I'm not talking about changing the Mapper, I want the same thing as you want, 
aka running another processor on the mapper side and I want to be able to do 
the same thing on the reducer side.
So instead of:
String defaultProcessor = jobConf.get("chukwa.demux.default.map.processor",
    
"org.apache.hadoop.chukwa.extraction.demux.processor.mapper.DefaultProcessor");

I was thinking of something like this (it's just another name for the config 
key):
String defaultProcessor = jobConf.get("chukwa.demux.processor.defaultMapper",
    
"org.apache.hadoop.chukwa.extraction.demux.processor.mapper.DefaultProcessor");


> Make default processor configurable

> The default processor is hard coded to {{DefaultProcessor}} in the {{Demux}} 
> class. This should be configurable.
