             Summary: Address confusing logging in o.a.n.net.URLExemptionFilters 
                 Key: NUTCH-3041
                 URL: https://issues.apache.org/jira/browse/NUTCH-3041
             Project: Nutch
          Issue Type: Task
          Components: net
    Affects Versions: 1.19, 1.20
            Reporter: Lewis John McGibbney
            Assignee: Lewis John McGibbney
             Fix For: 1.21


URLExemptionFilter impementations are used to allow exemptions to external domain resources by overriding the {{db.ignore.external.links}} configuration setting. This is useful when the crawl is focused to a domain but resources like images are hosted on CDN.

Currently [URLExemptionFilters|[https://github.com/apache/nutch/blob/271f92e11c39b7a3583cfcd8d664262cfac59674/src/java/org/apache/nutch/net/URLExemptionFilters.java#L47-L48]] provides some confusing INFO-level logging
{quote}INFO o.a.n.n.URLExemptionFilters [LocalJobRunner Map Task Executor #0] Found 0 extensions at point:'org.apache.nutch.net.URLExemptionFilter'
{quote}
I find this confusing. It would be better to log *only* if an URLExemptionFilter implementation actually exists for a given URL.

I will provide a patch for this.
