Doğacan Güney commented on NUTCH-247:
-------------------------------------
+1 for this approach.
Fetcher should check if agent-name is set (is setting agent-email necessary?)
before submitting the job to MR.
> robot parser to restrict.

> Key: NUTCH-247
> URL: https://issues.apache.org/jira/browse/NUTCH-247
> Project: Nutch
> Issue Type: Bug
> Components: fetcher
> Affects Versions: 0.8
> Reporter: Stefan Groschupf
> Priority: Minor
> Fix For: 0.9.0
>
>
> If the agent name and the robots agents are not proper configure the Robot
> rule parser uses LOG.severe to log the problem but solve it also.
> Later on the fetcher thread checks for severe errors and stop if there is one.
> RobotRulesParser:
> if (agents.size() == 0) {
> agents.add(agentName);
> LOG.severe("No agents listed in 'http.robots.agents' property!");
> } else if (!((String)agents.get(0)).equalsIgnoreCase(agentName)) {
> agents.add(0, agentName);
> LOG.severe("Agent we advertise (" + agentName
> + ") not listed first in 'http.robots.agents' property!");
> }
> Fetcher.FetcherThread:
> if (LogFormatter.hasLoggedSevere()) // something bad happened
> break;
> I suggest to use warn or something similar instead of severe to log this
> problem.
