Anton commented on NUTCH-1478:
-------------------------------
Hi [~lewismc] snipped of source code with NPE below.
I added comment to mark line 95 with NPE
{code:java}
// add the fields from contentmd
if (contentFieldnames != null) {
for (String metatag : contentFieldnames) {
// String[] value = parse.getData().getContentMeta().getValues(metatag);
ByteBuffer bvalues = page.getFromMetadata(new Utf8(metatag));
String value = new String(bvalues.array());
//line 95 with NPE
if (value != null)
doc.add("meta_" + metatag, value);
}
}
{code}
Hi [~talat] Do you mean that I need to define another field name in schema.xml?
I have such field definition now:
<field name="metatag.description" type="string" stored="true" indexed="true"/>
It have the same name as in wiki http://wiki.apache.org/nutch/IndexMetatags.
and another type of field ('string'), not the same as in wiki ('text')

> Project: Nutch
> Issue Type: Improvement
> Components: parser
> Affects Versions: 2.1
> Reporter: kiran
> Fix For: 2.3

>
> I have ported parse-metatags and index-metadata plugin to Nutch 2.x series.
> This will take multiple values of same tag and index in Solr as i patched
> before (https://issues.apache.org/jira/browse/NUTCH-1467).
> The usage is same as described here
> (http://wiki.apache.org/nutch/IndexMetatags) but one change is that there is
> no need to give 'metatag' keyword before metatag names. For example my
> configuration looks like this
> (https://github.com/salvager/NutchDev/blob/master/runtime/local/conf/nutch-site.xml)
>
> This is only the first version and does not include the junit test. I will
> update the new version soon.
> This will parse the tags and index the tags in Solr. Make sure you create the
> fields in 'index.parse.md' in nutch-site.xml in schema.xml in Solr.
> Please let me know if you have any suggestions
> This is supported by DLA (Digital Library and Archives) of Virginia Tech.
