SOLR-9246: If the JDBCStream sees an unknown column type it will now throw a
detailed exception
> Errors for Streaming Expressions using JDBC (Oracle) stream source
> ------------------------------------------------------------------
>
> Key: SOLR-9246
> URL: https://issues.apache.org/jira/browse/SOLR-9246
> Project: Solr
> Issue Type: Bug
> Affects Versions: 6.0.1
> Environment: Windows 7
> Reporter: Hui Liu
> Assignee: Dennis Gove
> Attachments: Re Errors for Streaming Expressions using JDBC (Oracle)

>
> I have Solr 6.0.0 installed on my PC (windows 7), I was experimenting with
> ‘Streaming Expression’ by using Oracle jdbc as the
> stream source, but got 'null pointer' errors, below is the details on how to
> reproduce this error:
> 1. create a collection 'document6' which only contain long and string data
> type,
> schema.xml for Solr collection 'document6': (newly created empty collections
> with 2 shards)
> ===========================================================================================

> 2. create a new Oracle (version 11.2.0.3) table 'document6' that only contain
> columns whose jdbc type is long and string,
> create table document6
> (document_id number(12) not null,
> sender_msg_dest varchar2(256),
> recip_msg_dest varchar2(256),
> document_type varchar2(20),
> document_key varchar2(100));
> loaded 9 records;
> Oracle table 'document6': (newly created Oracle table with 9 records)
> =====================================================================
> QA_DOCREP@qlgdb1 > desc document6
> Name Null? Type

> Here is the feedback from Joel Bernstein:
> =======================================
> I think we're going to have to add some debugging into the code to find
> what's going on. On line 225 in JDBCStream it's getting the class name for
> each column. It would be good know what the class names are that the Oracles
> driver is returning.
> https://github.com/apache/lucene-solr/blob/releases/lucene-solr/6.0.0/solr/solrj/src/java/org/apache/solr/client/solrj/io/stream/JDBCStream.java
> We probably need to throw an exception that includes the class name to help
> users report what different drivers using for the classes.
