Subject [jira] [Commented] (SOLR-13255) LanguageIdentifierUpdateProcessor broken for documents sent with SolrJ/javabin
Date Fri, 01 Mar 2019 18:00:00 GMT


Jason Gerlowski commented on SOLR-13255:

Hey [~ahubold], have you had a chance to confirm whether 7.7.1 has fixed this issue for you?
 I trust Noble's fix, but there was a report on the mailing list this morning about a similar
ClassCastException on Solr 7.7.1 so I figured it was worth checking in to see if you'd tried
out the fix yet or had a chance to do so in the near future...

>            Assignee: Noble Paul
>            Priority: Blocker
>             Fix For: 8.0, 7.7.1
>         Attachments: SOLR-13255.patch, SOLR-13255.patch, SOLR-13255.patch
> 7.7 changed the object type of string field values that are passed to UpdateRequestProcessor
implementations from java.lang.String to ByteArrayUtf8CharSequence. SOLR-12992 was mentioned
on solr-user as cause.
> The LangDetectLanguageIdentifierUpdateProcessor still expects String values, does not
work for CharSequences, and logs warnings instead. For example:
> {noformat}
> 2019-02-14 13:14:47.537 WARN  (qtp802600647-19) [   x:studio] o.a.s.u.p.LangDetectLanguageIdentifierUpdateProcessor
Field name_tokenized not a String value, not including in detection
> {noformat}
> I'm not sure, but there could be further places where the changed type for string values
needs to be handled. (Our custom UpdateRequestProcessor are broken as well since 7.7 and it
would be great to have a proper upgrade note as part of the release notes)
