Hi Shashanka, All,
Thank you for your reply!
I'm using Nutch 1.19. I did the injection and segment generation using the
following commands:
bin/nutch inject crawl/crawldb urls
bin/nutch generate crawl/crawldb crawl/segments
When I run the fetch command, Nutch stops with errors about hung threads.
I've attached the fetch command output and the nutch-site.xml.
s1=`ls -d crawl/segments/2* | tail -1`
bin/nutch fetch $s1
My questions are:
1) What do I need to do to get Nutch to continue working even if there are
hung threads?
2) Is there a way to avoid having these hanging threads in the first place?
Thank you
Sheham
