Subject [jira] Created: (NUTCH-601) Recrawling on existing crawl directory using force option
Date Mon, 04 Feb 2008 18:09:08 GMT
Recrawling on existing crawl directory using force option
---------------------------------------------------------

                 Key: NUTCH-601
                 URL: https://issues.apache.org/jira/browse/NUTCH-601
             Project: Nutch
          Issue Type: Improvement
    Affects Versions: 1.0.0
            Reporter: Susam Pal
            Priority: Minor


Added a '-force' option to the 'bin/nutch crawl' command line. With this option, one can crawl
and recrawl in the following manner:

{code}
bin/nutch crawl urls -dir crawl -depth 2 -topN 10 -threads 5
bin/nutch crawl urls -dir crawl -depth 2 -topN 10 -threads 5 -force
{code}

This option can be used for the first crawl too:

{code}
bin/nutch crawl urls -dir crawl -depth 2 -topN 10 -threads 5 -force
bin/nutch crawl urls -dir crawl -depth 2 -topN 10 -threads 5 -force
{code}

If one tries to crawl without the -force option when the crawl directory already exists, he/she
finds a small warning along with the error message:

{code}
# bin/nutch crawl urls -dir crawl -depth 2 -topN 10 -threads 5
Exception in thread "main" java.lang.RuntimeException: crawl already
exists. Add -force option to recrawl.
       at org.apache.nutch.crawl.Crawl.main(Crawl.java:89)
{code}
