Hi Chris, I have experienced similar problems with this in the past, for example I was trying to crawl for the following URL(amongst others) http://www.scotland.gov.uk For a reason still unknown to me I was unable to do so, having experiemented a bit I found that appending the /Home to the URL atleast gave me some results, having looked at my hadoop.log I saw the following: 2010-12-06 12:33:33,031 INFO fetcher.Fetcher - fetching http://www.sabsm.co.uk/ 2010-12-06 12:33:33,031 INFO fetcher.Fetcher - fetching http://www.south-ayrshire.gov.uk/ 2010-12-06 12:33:33,031 INFO fetcher.Fetcher - fetching http://www.scotland.gov.uk/Home/ 2010-12-06 12:33:33,047 INFO fetcher.Fetcher - -finishing thread FetcherThread, activeThreads=9 2010-12-06 12:33:33,047 INFO fetcher.Fetcher - -finishing thread FetcherThread, activeThreads=6 2010-12-06 12:33:33,047 INFO fetcher.Fetcher - -finishing thread FetcherThread, activeThreads=4 2010-12-06 12:33:33,047 INFO fetcher.Fetcher - -finishing thread FetcherThread, activeThreads=7 2010-12-06 12:33:33,047 INFO fetcher.Fetcher - -finishing thread FetcherThread, activeThreads=8 2010-12-06 12:33:33,047 INFO fetcher.Fetcher - -finishing thread FetcherThread, activeThreads=3 2010-12-06 12:33:33,047 INFO fetcher.Fetcher - -finishing thread FetcherThread, activeThreads=5 2010-12-06 12:33:33,125 INFO http.Http - http.proxy.host = null 2010-12-06 12:33:33,125 INFO http.Http - http.proxy.port = 8080 2010-12-06 12:33:33,125 INFO http.Http - http.timeout = 10000 2010-12-06 12:33:33,125 INFO http.Http - http.content.limit = -1 2010-12-06 12:33:33,125 INFO http.Http - http.agent = WOMBRA/Nutch-1.2 2010-12-06 12:33:33,125 INFO http.Http - http.accept.language = en-us,en-gb,en;q=0.7,*;q=0.3 2010-12-06 12:33:33,125 INFO http.Http - protocol.plugin.check.blocking = false 2010-12-06 12:33:33,125 INFO http.Http - protocol.plugin.check.robots = false ..... 2010-12-06 12:33:34,248 INFO fetcher.Fetcher - -activeThreads=3, spinWaiting=0, fetchQueues.totalSize=0 2010-12-06 12:33:34,263 INFO fetcher.Fetcher - -finishing thread FetcherThread, activeThreads=2 2010-12-06 12:33:34,279 INFO fetcher.Fetcher - -finishing thread FetcherThread, activeThreads=1 2010-12-06 12:33:34,295 WARN regex.RegexURLNormalizer - can't find rules for scope 'fetcher', using default 2010-12-06 12:33:34,310 INFO fetcher.Fetcher - -finishing thread FetcherThread, activeThreads=0 2010-12-06 12:33:35,262 INFO fetcher.Fetcher - -activeThreads=0, spinWaiting=0, fetchQueues.totalSize=0 2010-12-06 12:33:35,262 INFO fetcher.Fetcher - -activeThreads=0 2010-12-06 12:33:35,933 WARN util.NativeCodeLoader - Unable to load native-hadoop library for your platform... using builtin-java classes where applicable 2010-12-06 12:33:36,338 INFO fetcher.Fetcher - Fetcher: finished at 2010-12-06 12:33:36, elapsed: 00:00:12 2010-12-06 12:34:48,081 INFO parse.ParseSegment - ParseSegment: starting at 2010-12-06 12:34:48 2010-12-06 12:34:48,081 INFO parse.ParseSegment - ParseSegment: segment: crawl/segments/20101206123213 2010-12-06 12:34:51,404 WARN util.NativeCodeLoader - Unable to load native-hadoop library for your platform... using builtin-java classes where applicable
From this I puzzled as to what was stopping the thread fetching the URL. Does your Hadoop.log look anything similar or does it simply fail to mention injected URLs?

There are currently 10 urls that I am injecting. The problem though is that when I look through the log, I only see 3 or 4 of them being fetched. What would cause this? There are no errors that I can find. My understanding is that on the first pass of the fetch, all urls that were injected should be fetched. Am I correct in thinking this?
