Subject [jira] Commented: (NUTCH-769) Fetcher to skip queues for URLS getting repeated exceptions
Date Tue, 01 Dec 2009 15:16:20 GMT

    [ https://issues.apache.org/jira/browse/NUTCH-769?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12784260#action_12784260

Andrzej Bialecki  commented on NUTCH-769:
-----------------------------------------

I had to apply this patch by hand, due to NUTCH-770. I also added conf/nutch-default.xml documentation.
This was committed in rev. 885785 - thanks!

> As discussed on the mailing list (see http://www.mail-archive.com/nutch-user@lucene.apache.org/msg15360.html)
this patch allows to clear URLs queues in the Fetcher when more than a set number of exceptions
have been encountered in a row. This can speed up the fetching substantially in cases where
target hosts are not responsive (as a TimeoutException would be thrown) and limits cases where
a whole Fetch step is slowed down because of a few queues.
> by default the parameter fetcher.max.exceptions.per.queue has a value of -1 and is deactivated.
