Attachment: nutch-1385.txt
> More robust plug-in order properties in "nutch-site.xml"
> --------------------------------------------------------
>
> Key: NUTCH-1385
> URL: https://issues.apache.org/jira/browse/NUTCH-1385
> Project: Nutch
> Issue Type: Improvement
> Components: indexer, parser
> Affects Versions: 1.5
> Reporter: Andy Xue
> Priority: Minor
> Labels: filter
> Attachments: nutch-1385.txt

>
> When listing multiple scoring filters in certain properties (listed below) in
> "nutch-site.xml", it is vital that no spaces/newlines/tabs are placed in
> front of the value content.
> E.g.:
> This is fine:
> <value>org.apache.nutch.scoring.opic.OPICScoringFilter myFilter</value>
> Either of these will generate an exception:
> <value> org.apache.nutch.scoring.opic.OPICScoringFilter myFilter</value>
> <value>
> org.apache.nutch.scoring.opic.OPICScoringFilter
> myFilter
> </value>
> Affects these properties in "nutch-site.xml":
> * indexingfilter.order
> * urlnormalizer.order
> * urlfilter.order
> * htmlparsefilter.order
> * scoring.filter.order
> Solution: replaced 'order.split("\\s+")' to 'order.trim().split("\\s+")'.
> Patch provided.
