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
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.
