Subject [jira] [Commented] (NUTCH-1854) ./bin/crawl fails with a parsing fetcher
Date Tue, 07 Apr 2015 01:19:12 GMT

    [ https://issues.apache.org/jira/browse/NUTCH-1854?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14482356#comment-14482356

Chris A. Mattmann commented on NUTCH-1854:
------------------------------------------

Lewis, what specific problems can it lead to, I'm interested? Asitang has been trying this
out and it's been working on small focused crawls, as long as we have downstream support for
e.g., checking for crawl parser, and then also in the later jobs, making sure that there is
(or isn't) a parse_text folder in the segments. How would that not solve the issues?

> If you run ./bin/crawl with a parsing fetcher e.g.
> <property>
> >   <name>fetcher.parse</name>
> >   <value>false</value>
> >   <description>If true, fetcher will parse content. Default is false,
> > which means
> >   that a separate parsing step is required after fetching is
> > finished.</description>
> > </property>
> we get a horrible message as follows
> Exception in thread "main" java.io.IOException: Segment already parsed!
> We could improve this by making logging more complete and by adding a trigger to the
crawl script which would check for crawl_parse for a given segment and then skip parsing if
this is present.
