Can anybody help me on this exception? Because of this exception index is
corrupted.

documents and there are urls in the DB then it it generates error while
removing duplicates. To get rid of error, I did an hack in dedup method of
DeleteDuplicates class
//Removing duplicates
try{
JobClient.runJob(job);
}catch(Exception e){
LOG.info("Dedup: Error occurred: "+e.getMessage());
}
This solves my problem.

I tried to added a meta-tag in my customized indexed filter. Based on URL
pattern, I added a meta-tag called 'indexit', with value true or false.
In the reduce() method indexer, I checked this meta-tag and accordingly indexed
the document or not, something like in the end of reduce() method
String indexIt = parse.getData().getMeta("indexit");
if(indexIt != null){
if(!Boolean.getBoolean(indexIt)){
return ;
}
}
This works, as the document does not get indexed. However , it gives IOException
Exception in thread "main" java.io.IOException: Job failed!
at org.apache.hadoop.mapred.JobClient.runJob(JobClient.java:604)
at org.apache.nutch.indexer.DeleteDuplicates.dedup(DeleteDuplicates.java:439)
at org.apache.nutch.crawl.Crawl.main(Crawl.java:135)
I understand that DeleteDuplicate tries to remove duplicates of some URLs, and
there are no documents indexed for these URLs , thats why it gives expection.
Any suggestion to run it gracefully, I mean is this the write way of
controlling index process of a document?
I would really appreciate your suggestions.

Hello Group,
I need to index URLs that matches a particular URL pattern and I have added the
pattern in crawl-urlfilter.txt e.g. I want to index all urls of www.test.com
that are sub directory of product so my regex is
+^http://www.text.com/products/.*
urls/my.txt contains following entry
http://www.text.com, that mean I want to start indexing from main page of
www.text.com. However nutch does not index anything and when I run nutch it says
No URLs to fetch - check your seed list and URL filters.
I am sure this muct have been answered. I have already searched archive but not
able to find any suggestion.
I would really appreciate if you can put your valuable suggestion or let me
know the classes to be looked into.
Thanks in advance.
