Otis Gospodnetic updated NUTCH-629:
-----------------------------------
Attachment: NUTCH-629.patch
> Detect slow and timeout servers and drop their URLs
> ---------------------------------------------------
>
> Key: NUTCH-629
> URL: https://issues.apache.org/jira/browse/NUTCH-629
> Project: Nutch
> Issue Type: Improvement
> Components: fetcher
> Reporter: Otis Gospodnetic
> Attachments: NUTCH-629.patch
>
>
> Fetch jobs will finish faster if we find a way to prevent servers that are
> either slow or time out from slowing down the whole process.
> I'll attach a patch that counts per-server exceptions and timeouts and tracks
> download speed per server.
> Queues/sservers that exceed timeout or download thresholds are marked as
> "tooManyErrors" or "tooSlow". Once they get marked as such, all of their
> subsequent URLs get dropped (i.e. they do not fetched) and marked GONE.
> At the end of the fetch task, stats for each server processed are printed.
> Also, I believe the per-host/domain/TLD/etc. DB from NUTCH-628 would be the
> right place to add server data collected by this patch.
