Is there a way to restart just the reduce part of the fetching process if it failed. The Map jobs for 5M pages completed but the reduce jobs failed late. Is there a way to recover this so I don't have to recrawl all 5M pages?
I'm sorry to say but it's not possible at the moment (I know the feeling ... :-/ ). This is a limitation in Hadoop, there have been recently some (as yet inconclusive) discussions on this.
