I am planning to do a huge crawl using Nutch (billions of URLs) and so need
to understand whether Nutch can handle restarts after a crash.


For single system, if I do Ctrl+C while Nutch is running and then restart
it, will it be possible for Nutch to detect where it has reached in last run
and start from that point onwards? Or will it be considered as new fresh


Also if I have 5 nodes running Nutch and doing the crawling, if one of the
node fails, should it be considered as total failure of Nutch itself? Or
should I allow other nodes to proceed further? Will I loose data gathered by
the failed node?
