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.
