[ http://issues.apache.org/jira/browse/NUTCH-258?page=comments#action_12414763 ]
Stefan Groschupf commented on NUTCH-258: ---------------------------------------- Scott, I agree with you. However we need a clean patch to solve the problem, we can not just comment things out of the code. So I vote for the issue and I vote to reopen this issue. > Once Nutch logs a SEVERE log item, Nutch fails forevermore > ---------------------------------------------------------- > > Key: NUTCH-258 > URL: http://issues.apache.org/jira/browse/NUTCH-258 > Project: Nutch > Type: Bug > Components: fetcher > Versions: 0.8-dev > Environment: All > Reporter: Scott Ganyo > Priority: Critical > Attachments: dumbfix.patch > > Once a SEVERE log item is written, Nutch shuts down any fetching forevermore. > This is from the run() method in Fetcher.java: > public void run() { > synchronized (Fetcher.this) {activeThreads++;} // count threads > > try { > UTF8 key = new UTF8(); > CrawlDatum datum = new CrawlDatum(); > > while (true) { > if (LogFormatter.hasLoggedSevere()) // something bad happened > break; // exit > > Notice the last 2 lines. This will prevent Nutch from ever Fetching again > once this is hit as LogFormatter is storing this data as a static. > (Also note that "LogFormatter.hasLoggedSevere()" is also checked in > org.apache.nutch.net.URLFilterChecker and will disable this class as well.) > This must be fixed or Nutch cannot be run as any kind of long-running > service. Furthermore, I believe it is a poor decision to rely on a logging > event to determine the state of the application - this could have any number > of side-effects that would be extremely difficult to track down.
