> Zero results problems difficult to troubleshoot due to lack of logging
> ----------------------------------------------------------------------
>
> Key: NUTCH-796
> URL: https://issues.apache.org/jira/browse/NUTCH-796
> Project: Nutch
> Issue Type: Improvement
> Components: searcher, web gui
> Affects Versions: 1.0.0, 1.1
> Environment: Linux, x86, nutch searcher and nutch webaps. v1.0, v1.1
> Reporter: Jesse Hires
> Assignee: Andrzej Bialecki
> Fix For: 1.1
>
> Attachments: logging.patch
>
>
> There are a few places where search can fail in a distributed environment,
> but when configuration is not quite right, there are no indications of errors
> or logging.
> Increased logging of failures would help troubleshoot such problems, as well
> as lower the "I get 0 results, why?" questions that come across the mailing
> lists.
> Areas where logging would be helpful:
> search app cannot locate search-servers.txt
> search app cannot find searcher node listed in search-server.txt
> search app cannot connect to port on searcher specified in search-server.txt
> searcher (bin/nutch server...) cannot find index
> searcher cannot find segments
> Access denied in any of the above scenarios.
> There are probably more that would be helpful, but I am not yet familiar to
> know all the points of possible failure between the webpage and a search node.
