crawl-tool.xml must be read before nutch-site.xml when invoked using crawl
command
----------------------------------------------------------------------------------
Key: NUTCH-735
URL: https://issues.apache.org/jira/browse/NUTCH-735
Project: Nutch
Issue Type: Bug
Components: web gui
Affects Versions: 1.0.0
Reporter: Susam Pal
Priority: Minor
The inline documentation of 'conf/crawl-tool.xml' mentions:
{code:xml}
<!-- Do not modify this file directly. Instead, copy entries that you -->
<!-- wish to modify from this file into nutch-site.xml and change them -->
<!-- there. If nutch-site.xml does not already exist, create it. -->
{code}
However, I don't see any way of overriding the properties defined in
'conf/crawl-tool.xml' as 'conf/nutch-site.xml' is added to the configuration
before 'conf/crawl-tool.xml' in the code. Here are the relevant code snippets:
*src/org/apache/nutch/crawl/Crawl.java:*
{code:java}
Configuration conf = NutchConfiguration.create();
conf.addResource("crawl-tool.xml");
JobConf job = new NutchJob(conf);
{code}
*src/org/apache/nutch/tool/NutchConfiguration.java:*
{code:java}
conf.addResource("nutch-default.xml");
conf.addResource("nutch-site.xml");
{code}
I have fixed this in the attached patch. 'crawl-tool.xml' is now added to the
configuration before 'nutch-site.xml' only if crawl is invoked using the
'bin/nutch crawl' command.
