> Key: NUTCH-631
> URL: https://issues.apache.org/jira/browse/NUTCH-631
> Project: Nutch
> Issue Type: Bug
> Components: indexer
> Affects Versions: 1.0.0
> Environment: Verified on CentOS and OSX
> Reporter: Stefan Will
> Fix For: 1.0.0
>
>
> I did a simple crawl and started the indexer with the index-more plugin
> activated. The index job fails with the following stack trace in the task log:
> java.util.NoSuchElementException
> at java.util.TreeMap.key(TreeMap.java:433)
> at java.util.TreeMap.firstKey(TreeMap.java:287)
> at java.util.TreeSet.first(TreeSet.java:407)
> at
> java.util.Collections$UnmodifiableSortedSet.first(Collections.java:1114)

> I traced this down to the part in MoreIndexingFilter where the mime type is
> split into primary type and subtype for indexing:
> contentType = mimeType.getName();
> String primaryType = mimeType.getSuperType().getName();
> String subType = mimeType.getSubTypes().first().getName();
> Apparently Tika does not have a subtype for text/html. Furthermore, the
> supertype for text/html is set as application/octet-stream, which I doubt is
> what we want indexed. Don't we want primaryType to be "text" and subType to
> be "html" ?
> So I changed the code to:
> contentType = mimeType.getName();
> String[] split = contentType.split("/");
> String primaryType = split[0];
> String subType = (split.length>1)?split[1]:null;
>
> This does what I think it should do, but perhaps I'm missing something ?
