> We should upgrade to the new Hadoop API for Nutch trunk as already has been 
> done for the Nutchgora branch. If i'm not mistaken we can already upgrade to 
> the latest 0.20.5 version that still carries the legacy API so we can, 
> without immediately upgrading to 0.21 or higher, port the jobs to the new API 
> without having the need for a separate branch to work on.
> To the committers who created/ported jobs in NutchGora, please write down 
> your advice and experience.
