Subject [jira] [Updated] (ANY23-248) NTriplesWriter on hadoop : issue with MIME type
Date Mon, 02 Feb 2015 06:01:35 GMT

     [ https://issues.apache.org/jira/browse/ANY23-248?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Souri updated ANY23-248:
------------------------
    Description: 
I am trying to create n-triples from an html string. I am using the following code to do it:

StringDocumentSource documentSource = new StringDocumentSource(html, null);

            ByteArrayOutputStream out = new ByteArrayOutputStream();
            final NTriplesWriter tripleHandler = new NTriplesWriter(out);
            Any23 runner = new Any23();
           
            runner.extract(documentSource,tripleHandler);
            tripleHandler.close();
            String result = out.toString("us-ascii");
            return result;

This is giving me the error :

java.lang.NullPointerException
	at org.apache.any23.extractor.SingleDocumentExtraction.filterExtractorsByMIMEType(SingleDocumentExtraction.java:421)
	at org.apache.any23.extractor.SingleDocumentExtraction.run(SingleDocumentExtraction.java:223)
	at org.apache.any23.Any23.extract(Any23.java:298)
	at org.apache.any23.Any23.extract(Any23.java:433)


I am running this in hadoop. When I run locally with a single file it works, but doesn't work
when run on hadoop.

Can someone please tell me how to go about this issue?
