-------------------------------------
I think this is no longer an issue in 2.0. You can just do CTRL+C or kill-job
and nutch will resume from (nearly) the interrupted position now.

> How we can stop running nutch instance in local mode and in reducer mode
> without breaking the crawled data?
> For example, you push a list of site that take a long time to complete crawl;
> then you want to stop nutch instance suddenly ...
> - For local mode, I suggest as below
> We create a stop.txt file in specific directory, then for a piece of time,
> nutch instance will check whether this file existed or not; if existed, nutch
> instance will stop itself normally
> - For reducer mode, may we use zookeper to keep state of each instance?
> Any other suggestion?
> Thanks,
