[jira] [Updated] (ANY23-248) NTriplesWriter on hadoop : issue with
MIME type
[ 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?
