How parallel is parallel in your case ?
Don't forget Hadoop in distributed mode will serialize your jobs anyhow.
For the rest why don't you create two Nutch directories and run things
totally independently

Subject: Two Nutch parallel crawl with two conf folder.
Hi,
I want to do two Nutch parallel crawl with two conf folder.
I am using crawl command to do this. I have two separate conf folders, all
files from conf are same except crawl-urlfilter.txt . In this file we have
different filters(domain filters).
e.g . 1 st conf have -
+.^http://([a-z0-9]*\.)*abc.com/
2nd conf have -
+.^http://([a-z0-9]*\.)*xyz.com/
I am starting two crawl with above configuration and on separate
console.(one followed by other)
I am using following crawl commands -
bin/nutch --nutch_conf_dir=/home/conf1 crawl urls -dir test1 -depth 1
bin/nutch --nutch_conf_dir=/home/conf2 crawl urls -dir test2 -depth 1
[Note: We have modified nutch.sh for '--nutch_conf_dir']
urls file have following entries-
http://www.abc.com
http://www.xyz.com
http://www.pqr.com
Expected Result:
CrawlDB test1 should contains abc.com's data and CrawlDB test2 should
contains xyz.com's data.
Actual Results:
url filter of first run is overridden by url filter of second run.
So Both CrawlDB have xyz.com's data.
Please provide pointer regarding this.
Thanks in advance.
