help needed - adaptive refetch

[D . Saravanaraj]

hi,

after applying adaptive refetch patch to nutch mapred, for the first time i
called the crawl command as i have to initialize the crawldb...
the next time, i comment out the following lines in
org.apache.nutch.crawl.Crawl.java

if (fs.exists(dir)) {
         throw new RuntimeException(dir + " already exists.");
}

and

new Injector(job).inject(crawlDb, rootUrlDir);

But i find, the files are fetched even though they were nt modified. how to
use the same crawldb and using the same for further crawls in mapred
versions?


thanks
